Oct.13--Naming Acids

Compounds with hydrogen ions and a negatively charged ion can form acids when dissolved in water. At the same time, ions are separated from each other.

* H+ ion joins with H2O to from H3O+ (hydronium ion)
 For example, HCl (g) + H2O (l) à H3O+ (aq) + Cl- (aq)


How To Name Simple Acids:

1. Use “hydro” as the beginning.

2. Last syllable of the non metal is dropped and replaced with “-ic”.

3. Add “acid” at the end.

( _ide = hydro_ ic acid )

For example: HF = hydrofluoric acid
                        H2S = hydrosulphuric acid



How To Name Complex Acids:

1. change “-ate” into “-ic
change “-ite” into “-ious”

2. Add “acid” at the end of the name
