C08-0074. Consider three possible ionic compounds formed by barium and oxygen Ba O, Ba O, and Ba O . (a) Which would have the greatest lattice energy (b) Which would require the least energy to form the ions (c) Which compound actually exists, and why ... [Pg.562]

When a substance made up of ions is dissolved in water, the dissolved ions behave independently. That is, they undergo their own characteristic reactions regardless of what other ions may be present. For example, barium ions in solution, Ba2, always react with sulfate ions in solution, S04 , to form an insoluble ionic compound, BaS04(s), no matter what other ions are present in the barium solution. If a solution of barium chloride, BaCK, and a solution of sodium sulfate, Na S04, arc mixed, a white solid, barium sulfate, is produced. The solid can be separated from the solution by filtration, and the resulting solution contains sodium chloride, just as it would if solid NaCl were added to water. In other words, when the two solutions are mixed, the following reaction occurs ... [Pg.153]

Barium sulfate, BaS04, is a sparingly soluble ionic compound that is used to enhance X-ray imaging. [Pg.430]

Barium ions carry a 2+ charge, and nitrogen ions carry a 3— charge. What would be the chemical formula for the ionic compound barium nitride ... [Pg.214]

Compound (a) is composed of a metal (barium) and a nonmetal (fluorine) and is likely to be ionic. Compounds (b)-(d) are composed entirely of nonmetals and therefore are probably molecular. [Pg.55]

Ionic compounds containing polyatomic ions (Section 2.8) are named in the same way as binary ionic compounds First the cation is identified and then the anion. For example, Ba(N03)2 is called barium nitrate because Ba2+ is the cation and the N03 polyatomic anion has the name nitrate. Unfortunately, there is no systematic way of naming the polyatomic ions themselves, so it s necessary to memorize the names, formulas, and charges of the most common ones listed in Table 2.3. The ammonium ion (NH4+) is the only cation on the list all the others are anions. [Pg.60]

Write the formulas for the following ionic compounds (a) barium oxide (b) aluminum chloride (c) magnesium phosphate. [Pg.145]

Note how the barium and potassium ions have simply been exchanged between the two negative ions. Also note that on both sides of the equation there are two ionic compounds. This is a good indicator that an equation represents a double-replacement reaction. [Pg.243]

Some types of ionic compounds can absorb water so that each formula unit is attached to a specific number of water molecules. They are called hydrates. Ba0H2 8H20 is called barium hydroxide octahydrate. CaS04 2H20 is called calcium sulfate dihydrate. Can you see the pattern Try naming MgS04 7H20. Use Table 3.8 to help you. You will learn more about hydrates in Chapter 6. [Pg.103]

Write the chemical formulas for calcium chloride and ammonium sulfate. Predict what kind of reaction will occur between them. Write a balanced chemical equation to show the reaction. Ionic compounds containing the ammonium ion are soluble. Ammonium sulfate is soluble, but barium chloride is not. [Pg.185]

Scientists also use the simplest formula to represent one mole of an ionic compound. They often use the term formula unit when referring to ionic compounds, because they are not found as single molecules. A formula unit of an ionic compound represents the simplest ratio of cations to anions. A formula unit of KBr is made up of one ion and one Br ion. One mole of an ionic compound has 6.022 x 10 of these formula units. As with molecular compounds, the molar mass of an ionic compound is the sum of the masses of all the atoms in the formula expressed in g/mol. Table 1 compares the formula units and molar masses of three ionic compounds. Sample Problem F shows how to calculate the molar mass of barium nitrate. [Pg.256]

Notice in Table 1 that the same about 25 joule rule also applies to the molar heat capacities of solid ionic compounds. One mole barium chloride has three times as many ions as atoms in 1 mol of metal. So, you expect the molar heat capacity for BaCl2 to be C = 3 x 25 J/K mol. The value in Table 1,75.1 J/K mol, is similar to this prediction. [Pg.361]

Explain the formation of an ionic compound from barium and nitrogen. [Pg.874]

To name an ionic compound, just put tire cation name in front of the anion name as in barium sulfate (BaS04) or sodium hydride (NaH). [Pg.12]

When a substance made up of ions is dissolved in water, the dissolved ions undergo their own characteristic reactions regardless of what other ions may be present. For example, barium ions in solution always react with sulfate ions in solution to form an insoluble ionic compound. [Pg.60]

In an aqueous solution, ionic compounds are completely dissociated into ions. For example, an aqueous solution of barium nitrate, Ba(N03)2, contains Ba + ions and NO3 ions. If aqueous solutions of ionic compounds are mixed, some ions may interact to form an insoluble product called a precipitate. For example, if aqueous solutions of barium nitrate and sodium sulfate are mixed, insoluble barium sulfate will precipitate. The complete formula equation for this reaction is written as follows. [Pg.456]

The barium sulfate is a white precipitate. Its formation as a result of mixing two unknown solutions could help you to identify the two reacting solutions. In this ChemLab, you will work with the aqueous solutions of six unknown ionic compounds. By observing the solutions and their interactions, you will be able to determine the identities of the compounds. [Pg.456]

When our family gets to the park, they find themselves a place on the lawn, which was fertilized with a mixture of ionic compounds, including iron(II) sulfate. They eat their dinner and play in the park until it s time for the fireworks. The safety matches used to light the rockets contain barium chromate, and ionic compounds in the fireworks provide the colors red from strontium chlorate, white from magnesium nitrate, and blue from copper(II) chloride. [Pg.94]

As stated earlier, ionic compounds are not made up of molecules rather, the smallest unit of an ionic compound is the formula unit that is given by the formula of the compound. Barium fluoride, BaF2, is an ionic compound and its formula unit, BaF2, is composed of one barium ion, Ba2+, and two fluoride ions, F . The molar mass of BaF2 is 175.3 g. [Pg.123]

A cautionary note In Chapter 15 (p. 600) we assumed that dissolved substances exhibit ideal behavior for our calculations involving solution concentrations, but this assumption is not always valid. For example, a solution of barium fluoride (BaF2) may contain both neutral and charged ion pairs, such as Bap2 and BaF, in addition to Ba + and F ions. Furthermore, many anions in the ionic compounds listed in Table 16.2 are conjugate bases of weak acids. Consider copper sulfide (CuS). The ion can hydrolyze as follows... [Pg.665]

Efficient methods for the isolation and purification of crown ethers by complexing with alkaline-earth salts or with non-ionic compounds have been reported. These methods allow the purification of 18-crown-6 without the need for potentially hazardous distillations. Barium methanedisulphonate is the best salt, and nitromethane the best non-ionic reagent, for purification of 18-crown-6. [Pg.431]

Solution (a) The charge of the Ba ion must be balanced by two C2H302 ions, so the prefix di- is unnecessary. For ionic compounds, we do not indicate the number of ions with numerical prefixes. The correct name is barium acetate. [Pg.56]

X 1.008 amu) -I- 16.00 amu = 18.02 amu Ionic compounds are treated the same, but because they do not eonsist of molecules, we use the term formula mass for an ionic compound. To calculate its formula mass, the number of atoms of each element inside the parentheses is multiplied by the subscript outside the parentheses. For barium nitrate, Ba(N03)2, Formula mass of Ba(N03)2... [Pg.58]

Evaporate the water from the above reaction mixture, and the ionic solid barium chloride remains. An ionic compound that results from the reaction of an acid and a base is called a salt. Thus, in a typical aqueous neutralization reaction, the reactants are an acid and a base, and the products are a salt solution and water ... [Pg.119]

Some ionic compounds, such as sodium chloride, dissolve readily in water, and some, such as barium sulfate (BaS04) barely dissolve at all. On dissolving, all ionic compounds dissociate into ions. [Pg.614]

The common ion effect also plays a role in the use of BaS04 when X rays of the digestive system are taken. The low solubility of BaS04 helps ensure that the amount of the toxic barium ion absorbed into patients system is small enough to be harmless. The procedure is further safeguarded by the addition of sodium sulfate (Na2S04), a soluble ionic compound that provides a common ion, S04 . ... [Pg.621]

Ionic compounds which are only slightly soluble in water are said to be sparingly soluble. Examples include silver chloride (Ag", Cl ) and barium sulfate (Ba ", S04 ). Since such compounds are only slightly soluble, the volume of water used to dissolve a salt may be taken to be equal to the volume of the solution. (For example, if we dissolve 0.0010 g of silver chloride in 1000 cm of water, we may safely assume that the volume of the solution is also 1000 cm. ) This approximation does... [Pg.176]

For these s-block elements, the stability of complexes is often affected by the difference in the size of the ionic radii relative to the cation and anion pair. Large anions are generally better stabilized by large cations for example, barium peroxide is more stable than beryllium peroxide. In fact, the barium peroxide compound is so stable that it forms spontaneously in air. [Pg.156]

Give the chemical formula for each of the following ionic compounds (a) sodium phosphate, (b) zinc nitrate, (c) barium bromate, (d) iron(II) perchlorate, (e) cobalt(II) hydrogen carbonate, (f) chromium(III) acetate, (g) potassium dichromate. [Pg.73]
