Naming Binary Acids

A binary acid is an acid that contains only two different elements hydrogen and one of the more electronegative elements. Many common inorganic acids are binary acids. The hydrogen hahdes—HE, HCl, HBr, and HI—are all binary acids. Names for some binary acids are given in Figure 1.3. 

Another binary mixture, namely, (acrylic acid/ acrylamide) was grafted onto carboxy methyl cellulose (CMC) [25]. 

Step 1 If the compound is a binary acid in solution, add hydro.. . ic acid to the root of the element s name. 

Many hydrogen compounds are acids. Acids require a different system of nomenclature than other compounds. There are two types of acids binary acids and ternary acids. All acids include the word acid in their name. Binary acids contain only two elements one of which is hydrogen and the other a nonmetal. When naming binary acids, the prefix hydro- appears before the root name of the nonmetal, and there will be an -ic suffix. As an acid, H2S would be hydrosulfuric acid. We used H2S to illustrate the fact that there can be two possible names, hydrogen sulfide or hydrosulfuric acid. If your instructor does not specify which name to use, either is correct. Technically, the name hydrosulfuric acid only applies to aqueous solutions of H2S, H2S(aq). 

J 1 Oxy-acids Oxy-acids contain hydrogen bonded to a polyatomic ion containing oxygen. To name a binary acid (no oxygen), use the following steps ... 

Hydrobromic acid. HBr is a binary acid it doesn t contain oxygen, so it isn t an oxy-acid. You begin by writing hydro-. Next, change the ending of the anion name, bromine, to -ic and write bromic after hydro- Write acid at the end, and you re done ... 

Write the proper names for the following binary acids ... 

Identify the anion for each oxy-acid from the polyatomic ion chart in Table 6-1. If the polyatomic ion ends in -ate, change the ending to -ic. If the polyatomic ion ends in -/Ye, change the ending to -ous. Write acid at the end of the name. (Don t begin with hydro- These aren t binary acids.)... 

Binary acids, acids that are formed from a hydrogen ion bonding to a monatomic anion, are named by placing the term hydro- in front of the root of the anion ending in -ic. For instance, HC1 is called hydrochloric acid. 

There are two main kinds of acids binary acids and oxoacids. A binary acid is composed of two elements hydrogen and a non-metal. Two examples of binary acids are hydrofluoric acid and hydrochloric acid. All binary acids have the general formula HX(aq). The H represents one or more hydrogen atoms. The X represents the non-metal. As you can see in Table 10.6, the names of binary acids are made up of the following parts ... 

As you know, anions are formed when binary acids dissociate. The names of these anions end in the suffix -ide. For example, hydroflouric acid forms the anion fluoride, F . Hydrochloric acid forms the anion chloride, Cl . 

Metal -nonmetal compounds and ammonium compounds (containing the NH4 group within a formula) are ionic. Other compounds are covalent, except that acids are ionized, some completely, when dissolved in water. The acids are named with a special system of their own, but pure binary acids can be named similarly to alkali metal-nonmetal compounds. 

The systematic names presented for binary nonmetal-nonmetal compounds are not used for the hydrogen compounds of group III, TV, and V elements or for water. These compounds have common names which are used instead. Water and ammonia (NH3) are the most important compounds in this class. See Sec. 6.4 for acid names. 

Water solutions of some molecules are acidic and are named as acids. Acids are important compounds with specific properties that will be discussed at length in Chapter 19. If the compound produces hydrogen ions (H+) in solution, it is an acid. For example, HCl produces H+ in solution and is an acid. Two common types of acids exist— binary acids and oxyacids. 

Naming binary acids A binary acid contains hydrogen and one other element. When naming a binary acid, use the prefix hydro- to name the hydrogen part of the compound. The rest of the name consists of a form of the root of the second element plus the suffix -ic, followed by the word acid. For example, HBr in a water solution is called hydrobromic acid. 

Although the term binary indicates exactly two elements, a few acids that contain more than two elements are named according to the rules for naming binary acids. If no oxygen is present in the formula for the acidic compound, the acid is named in the same way as a binary acid, except that the root of the second part of the name is the root of the polyatomic ion that the acid contains. For example, HCN, which is composed of hydrogen and the cyanide ion, is called hydrocyanic acid. 

Compare and contrast naming binary acids and naming other binary covalent molecules. 

Contains three elements but is named as a binary acid. 

Binary acids are compounds in which H is bonded to a Group VIA elemeut other than O or to a Group VILA element they act as acids when dissolved in water. The pure compounds are named as typical binary compounds. Their aqueous solutions are named by modifying the characteristic stem of the nonmetal with the prefix hydro- and the suffix -ic followed by the word acid. The stem for sulfur iu this iustauce is sulfur rather thau sulf. ... 

Objective 12 Binary acids are named by writing hydro followed by the root of the name of the halogen, then -ic, and finally acid (Table 5.2) ... 

You will be expected to be able to write formulas and names for the binary acids found on Table 5.2. Remember that it is a good habit to write aq) after the formula.
