The metal oxide is basic in nature. It mixes with water to form metal hydroxide as follows

MO + H2O → M(OH)2

Blue litmus does not change the colour in the basic medium.

What happens when Zn strip is dipped in CuSO4 solution ?

Zinc strip displaces or removes Copper from Copper sulphate solution and this reaction is known as displacement reactions. Zn(s)+CuSO4(sq) → ZnSO4(aq)+Cu(s)

An element X forms an oxide which turns red litmus blue. Identify whether X is a metal or non-metal.

Metal, because metal oxides are basic in nature.

A student puts a drop of reaction mixture of a saponification reaction first on a blue litmus paper and then on a red litmus paper.

There is no change in blue litmus paper as soap solution is alkaline in nature.

Dry ammonia has no action on litmus paper but a solution of ammonia in water turns red litmus paper blue. Why is it so?

In dry state Ammonia contains no hydroxyl ions. On dissolving in water, it forms NH4OH which dissociates to give NH4 + and OH-ions. Thus solution becomes basic and turns red...
