Yes, Lithium oxide is basic as it dissolves in pure water, the resulting solution has a pH value greater than 7.0. It forms Lithium hydroxide when added to water, which is alkaline.

Good Luck!!

Lithium oxide is a basic oxide When it dissolves in pure water, the resulting solution has a pH value greater than 7.0.

It is a strong base. It is corrosive when dissolved in water. Lithium oxide dissolves in water to make lithium hydroxide. It reacts with acids to make lithium salts.

Hope this helps!!!
