Ammonium sulfate [7783-20-2], (NH 2 U4, is a white, soluble, crystalline salt having a formula wt of 132.14. The crystals have a rhombic stmcture d is 1.769. An important factor in the crystallization of ammonium sulfate is the sensitivity of its crystal habit and size to the presence of other components in the crystallizing solution. If heated in a closed system ammonium sulfate melts at 513 2° C (14) if heated in an open system, the salt begins to decompose at 100°C, giving ammonia and ammonium bisulfate [7803-63-6], NH HSO, which melts at 146.9°C. Above 300°C, decomposition becomes more extensive giving sulfur dioxide, sulfur trioxide, water, and nitrogen, in addition to ammonia. [Pg.367]

Compounds containing polyatomic ions follow similar rules. In sodium carbonate, there are two Na+ ions per carbonate ion, so its formula is Na2C03. When a subscript has to be added to a polyatomic ion, the ion is written within parentheses, as in (NH4)2S04, where (NH4)2 means that there are two NH4+ (ammonium) ions for each S042- (sulfate) ion in ammonium sulfate. In each case, the ions combine in such a way that the positive and negative charges cancel all compounds are electrically neutral overall. [Pg.65]

We do not speak of a molecule of an ionic compound. However, it is useful to be able to refer to a representative group of ions with the number of atoms given by the formula. This group of ions- is called a formula unit. For example, the formula unit of sodium chloride, NaCl, consists of one Na+ ion and one Cl ion and the formula unit of ammonium sulfate, (NH4)2S04, consists of two NH4+ ions and one S042- ion.

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]

Assay With the aid of about 25 mL of water, transfer about 125 mg of sample, accurately weighed, into a 300-mL Erlen-meyer flask. Add 50.0 mL of 0.5 N potassium dichromate, mix, then carefully add 100 mL of sulfuric acid, and heat to boiling. Remove the mixture from the heat, allow it to stand at room temperature for 15 min, cool it in a water bath, and transfer it into a 250-mL volumetric flask. Dilute almost to volume with water, cool to 25°, then dilute to volume with water, and mix. Titrate a 50.0-mL aliquot with 0.1 iV ferrous ammonium sulfate, using 2 or 3 drops of orthophenanthroline TS as the indicator, and record the volume required, in milliliters, as S. Perform a blank determination (see General Provisions), and record the volume of 0.1 N ferrous ammonium sulfate required, in milliliters, as B. Calculate the percent cellulose in the sample by the formula... [Pg.107]

Sodium Chloride Content Accurately weigh about 20 mg of sample, and dissolve it in 50 mL of water contained in a glass-stoppered flask. Add, while agitating, 3 mL of nitric acid, 5 mL of nitrobenzene, 50.0 mL of 0.1 N silver nitrate, and 2 mL of ferric ammonium sulfate TS. Shake well, and titrate the excess silver nitrate with 0.2 N ammonium thiocyanate. The titration endpoint is indicated by the appearance of a red color. Perform a blank determination (see General Provisions). Calculate the content of sodium chloride in the sample by the formula... [Pg.303]

Example 1 Find the molar mass of (NH4)2S04. Counting all the atoms in the formulas of some ionic compounds requires care. This is because many ionic compounds contain multiple polyatomic ions. The formula of ammonium sulfate, (NH4)2S04, is made up of three polyatomic ions, two ammonium ions, NH4+, and one sulfate ion, S04z . There is a total of 15 atoms in the formula unit, and each atom contributes to the formula mass of the compound. Two NH4+ ions = 2 N atoms and 8 H atoms one S042 ion = 1 S atom and 4 O atoms. The sum of the atomic masses can be symbolized ... [Pg.119]
