Question

A small amount of solution hydroxide solution is added to a small piece of granulated zinc metal is a test tube which of the following represent correct equation​

Answer 1

Explanation:

Explanation: Sodium hydroxide solution is added to a few pieces of granulated zinc metal taken in a test tube.

Zn(s)Zinc + 2NaOH(aq)sodium hydroxide →Na2ZnO2(aq) sodium zincate + H2(g)Hydrogen

Answer 2

Answer:

When zinc is added in sodium solution sodium zincate (Na
