Question

Does metal react with bases or not? Why?

Answer 1

Yes metal reacts with base

Reaction of Base with Metals:

When alkali (base) reacts with metal, it produces salt and hydrogen gas.

Alkali + Metal ⇨ Salt + Hydrogen

Example: Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal.

2NaOH + Zn ⇨ Na2ZnO2+ H2

Sodium aluminate and hydrogen gas are formed when sodium hydroxide reacts with aluminium metal.

2NaOH + 2Al + 2H2O ⇨ 2NaAlO2+ 2H2
