Question

Hello everyone !!!



Write an activity to show how metals and non metals react with sodium hydroxide.

Answer 1

Sodium reacts less strongly than potassium, for example. Reaction with cold water. All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced.

Answer 2

Hey mate!!!
Here's your answer...

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

Hope this will help you.
