Chemical Properties of acid


Action on Metals

a) Metals above hydrogen in the metal activity series generally react with dilute acids to form their respective salt and hydrogen.

Metal + Acid Salt + Hydrogen



b) Very active metals like potassium, sodium and calcium also react similarly, but tend to explode when combining with acids

.

c) Nitric acid (of variousconcentrations) usually exhibits oxidizing property, rather than acidic properties. Metals such as magnesium combine with extremely dilute (1%) nitric acid to liberate hydrogen.

Action with Basic Oxides

Oxides that can add on hydroxyl ions to their molecules are called basic oxides. These oxides get neutralized when they react with acids.

Basic oxide + Acid Salt + Water




Action with Basic Hydroxides

Acids undergo neutralization reaction with basic hydroxides to form salt and water.

Basic hydroxide + Acid Salt + Water





Action with Carbonates and Hydrogen carbonates

Acids react with carbonates and hydrogen carbonates to form their respective salt, water and carbon dioxide.

Carbonate/Bicarbonate + Acid Salt + Water + Carbon dioxide





Action with Sulphites and Bisulphites

Acids react with sulphites and bisulphites to form their respective salt, water and sulphur dioxide.

Sulphite/Bisulphites + Acid Salt + Water + Sulphur dioxide





With Metal Sulphides

Acids react with metal sulphides to form their respective salt and hydrogen sulphide.


Metals sulphide + Acid Salt + Hydrogen sulphide
