Question

explain the reaction of sodium zincate in easy sentences​

Answer 1

Answer:

Explanation:

When alkali (base) reacts with metal, it produces salt and hydrogen gas. Example: Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal. Sodium aluminate and hydrogen gas are formed when sodium hydroxide reacts with aluminium metal.

Answer 2

Answer:

When a base reacts with a metal, then a metal salt and hydrogen gas are formed. ... In the salt formed by the reaction between a base and a metal, the metal is present as a part of the negative ion.

In the sodium zincate salt (Na2ZnO2), the zinc metal is present as a part of the negative ion, zincate ion (ZnO22-).
