How to name and write acids and bases

If the ion has two less oxygen atoms than the "-ate" ion, tack on the prefix "hypo-" and use the "-ous" ending.

How to write acid formulas

Selenate ends in -ate, so the name of the parent acid ends in -ic. When such a compound dissolves in water to form an acid, the polyatomic ion is the anion. Ammonia and ammonium hydroxide do, however, behave quite differently under other circumstances, as, for example, in their pure forms ammonia is a gas and ammonium hydroxide is a solid or when they are dissolved in solvents other than water. It has the formula NH3 and is the simplest member of a family of bases called the amines. They are acetate, carbonate, nitrate, phosphate, sulfate, and chlorate. For example, the compound HCl is composed of hydrogen and chlorine, and in solution it produces a strong acid. Therefore, strong bases are named following the rules for naming ionic compounds. For example, NH4OH is ammonium hydroxide.

The acid formed from the sulfate ion is called sulfuric acid, while the acid formed from the phosphate ion is called phosphoric acid. His writing covers science, math and home improvement and design, as well as religion and the oriental healing arts.

Naming Acids Acids are named by the anion they form when dissolved in water. Most non-metal atoms that form polyatomic ions form more than one polyatomic ion.

How to name and write acids and bases

If the anion has one more oxygen atom than an "-ate" ion, add the prefix "per-. Most non-metal atoms that form polyatomic ions form more than one polyatomic ion. The anion is the prime consideration when naming the acid. Convert between the structure of an acid or base and its chemical name Key Points Acids are named based on their anion — the ion attached to the hydrogen. The acid is therefore selenic acid H2SeO4. Complex acid compounds have oxygen in them. Term polyatomic ionA charged species ion composed of two or more atoms covalently bonded. Be careful to note that the Roman numeral in parentheses following the metal ion does not, strictly speaking, refer to the number of hydroxide ions. Nomenclature of common acidsThis chart provides the nomenclature of some common anions and acids More complex acids have oxygen in the compound. It has the formula NH3 and is the simplest member of a family of bases called the amines. When it does this, it also releases the ions to which the hydrogens were bound before the compound was put in solution.

Naming Bases Naming Acids Naming Salts Naming Bases The easiest are the bases, since most of these are metal hydroxides, compounds you already know how to name.

In fact, solutions of ammonia in water and solutions of ammonium hydroxide in water are indistinguishable. For example, methyl amine CH3NH2 is a weak base.

Concentrated aqueous solutions of ammonia NH3 contain significant amounts of the hydroxide ion, even though the dissolved substance is not primarily ammonium hydroxide NH4OH as is often stated on the label.
