Detailed Solution

The above statement is true.
Metallic oxides are basic. Therefore, basic solutions turn red litmus paper blue. Magnesium oxide is a metal oxide, so it is basic. When touched with its aqueous solution, its basic character causes it to turn red litmus blue. Because it contains oxide ions, magnesium oxide is a simple basic oxide. It combines with water to form magnesium hydroxide, a base. The reaction is:
MgO + H2O → Mg (OH)2
