Hydro ic acid

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

If the anion ends in -ide, add the prefix hydro- and change the ending to "-ic acid."... 

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 ... 

In addition to the oxoacids, there are a small number of other acids, such as HC1, that do not contain oxygen. Although the pure, gaseous compound HC1 is named hydrogen chloride according to the rules for binary compounds, the aqueous solution is named hydrochloric acid, HCl(a ). This example is typical of non-oxygen-containing acids The prefix hydro- and the suffix -ic acid are used for the aqueous solution in such cases. 

To name an acid, look at the formula and decide whether the compound is an oxoacid. If so, the name must reflect the number of oxygen atoms, according to Table 2.4. If the compound is not an oxoacid, it is named using the prefix hydro- and the suffix -ic acid. 

FD C Blue No. 2 is principally the disodium salt of 2-(l,3-dihydro-3-oxo-5-sulfo-2//-indol-2-ylidene)-2,3-dihydro-3-oxo-1 //- i n do I c-5 - s u I lb n ic acid, with smaller amounts of the disodium salt of 2-fl, 3-d i hydro-3-oxo-7-sulfo-2//-indol-2-y I idcne)-2,3-dihydro-3-oxo-l//-indole-5-sulfonic acid and the sodium salt of 2-(l,3-dihydro-3-oxo-2//-indol-2-ylidene)-2,3-dihydro-3-oxo-l//-indole-5-sulfonic acid. 

For anions ending in -ide, use a hydro- prefix and an -ic acid ending. For example, what is the chemical name for HCl and HCN ... 

Ans. (a) HBr is related to Br , the bromide ion. The -ide ending is changed to -ic acid and the prefix hydro- is added. The name is hydrobromic acid.

Solution (a) HI is related to I , the iodide ion. The -ide ending is changed to -ic acid and the prefix hydro- is added. The name is hy-droiodic acid. (Z ) 11 (), is related to NO,, the nitrate ion. The -ate ending is changed to -ic acid. Tlie name is nitric acid, (c) HCIO is related to CIO 1. the perchlorate ion. Fhe prefix per- is not changed, but the ending is changed to -ic acid. Tlie name is perchloric acid.

The binary acids are named by adding the prefix hydro- to the stem of the nonmetal followed by the -ic ending then adding the word acid. Hydrogen chloride, HC1, becomes hydro- chlor -ic acid, HCl(aq).

Two types of acids are named differently. Water solutions of binary covalent compounds containing hydrogen and a nonmetal are named following the pattern hydro(stem)ic acid, where (stem) is the stem of the name of the nonmetal bonded to hydrogen. Acids in which hydrogen is bonded to polyatomic ions have names based on the name of the polyatomic ion to which hydrogen is bonded. 

The prefix and suffix hydro- and -ic indicate that all oxygen is removed from the -ic acid thus, the formula is HCl. 

A salt derived from a hydracid is named according to the nonmetal present in the parent acid, and the salt will end in - ide . The metallic part of the salt is named first. The prefix hydro is dropped and suffix - ic (of the acid) is changed to - ide . HC1 HBr HCN H2S Sodium chloride (NaCl) Magnesium chloride (MgCl2) Potassium bromide (KBr) Zinc bromide (ZnBr2) Sodium cyanide (NaCN) Potassium sulfide (K2S)... 

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). 

Identify the anion for each bineiry acid. Add hydro- to the beginning of it and change the ending of it to -ic (if necessary, drop the o in hydro- to avoid having two vowels next to each other). Then write acid at the end. 

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.)... 

These acids are named by putting the prefix hydro- before the rest of the name of the characteristic element (or elements) and adding the suffix -ic.
