Answer:

The solution of ash obtained after burning magnesium ribbon in the air is classified as a base. When magnesium burns in air, it reacts with oxygen to form magnesium oxide (MgO). When this oxide dissolves in water, it forms magnesium hydroxide (Mg(OH)₂), which is a strong base. Since a base turns blue litmus paper red, the solution of magnesium oxide is basic.

Explanation:

When magnesium burns in air, it reacts with oxygen to form magnesium oxide (MgO). This oxide is a basic oxide. When magnesium oxide is dissolved in water, it reacts to form magnesium hydroxide (Mg(OH)₂), which is a base.

The reason the blue litmus paper turns red is that magnesium hydroxide is a base and bases turn blue litmus paper red. This indicates that the solution resulting from the reaction of magnesium oxide with water is basic.
