Question

the red litmus paper turns blue when it is is dipped into the solution of magnesium oxide with water​

Answer 1

Answer:

So, the given acidic oxide of carbon, i.e., carbon dioxide turns blue litmus red.

Explanation:

Metal oxides are basic oxides. MgO is also a basic oxide but not as strong as sodium oxide. So on dissolution, it will produce magnesium hydroxide which is a base and the solution will be basic in nature. So it will change the color of red litmus paper to blue, and blue will remain the same.
