Question

What will happen when ash of magnesium is dissolved in water? Is solution acidic or basic? What effect does litmus show in case of oxides of metal?

Answer 1

Hi dear,✋✋

Here's the answer:-

Ash of magnesium is MgO. When it dissolves ie reacts with water, it forms Magnesium Hydroxide.

The reaction :-

MgO + H2O ---> Mg(OH)2

This solution is basic as all hydroxides are basic in nature.

Oxides of all metals are bases except some which stay generally inert .

Let's see how:-

Na2O is sodium oxide . This when tested with moist red litmus, turns into blue color.

HOPE THESE ALL FACTS HELP YOU ☺

Answer 2

It will form magnesium hydroxide and hydrogen.
It is a basic solution and will turn litmus blue.
In the case of oxides of metals, as they are basic, so litmus will turn blue except a few like lead (iv) oxide.
