Question

Explain with a help of equation a metal react with a base?

Answer 1

When base(2NaOH) and metals(Zn )react they forms a salt(Na2ZNO2) and hydrogen gas is also liberated.

Here Na2ZNO2 is sodium zincate which is a salt.

Hope this will help to all

Answer 2

Metals generally react with acids but some metals like zinc react with bases such metals are amphoteric in nature.

Reaction of zinc with sodium hydroxide.

The equation is as follows:

Zn + NaOH →$Na_{2}Zn O_{2} + H_{2}$

When granulated zinc is warmed with sodium hydroxide solution , sodium zincate is formed along with hydrogen gas.

This depicts the reaction between a metal and a base.
