Acid, Base & Salt

Chemical Properties

How do Acids and Bases React with Metals?

Acids and bases give hydrogen gas and respective salt when reacts with most of the metals. General reaction for acid and base with metals can be depicted as follows:

Acid + Metal → Salt + Hydrogen

Base + Metal → Salt + Hydrogen

Some metals do not react with acid and base.

Examples:

Reactions of acid with metals

(1) When zinc metal reacts with hydrochloric acid, zinc chloride (a salt) and hydrogen gas are formed.

(2) When zinc metal reacts with sulphuric acid, zinc sulphate (a salt) and hydrogen gas are formed.

(3) When sodium metal reacts with hydrochloric acid, sodium chloride and hydrogen gas are formed.

(4) When iron metal reacts with hydrochloric acid solution of iron chloride and hydrogen gas is formed.

Reaction of base with metals

(1) When sodium hydroxide reacts with zinc metal, it produces sodium zincate and hydrogen gas.

(2) When sodium hydroxide reacts with aluminium, it produces hydrogen gas and sodium aluminate.

Since, alkalis react with metals, so alkalis are not stored in metal containers.
