Barium Oxide and Water Reactions

The video explores whether barium oxide (BaO) is soluble in water. Initially, solubility rules provide little guidance, so a solubility table is consulted. It is revealed that barium oxide reacts with water rather than dissolving, forming barium hydroxide. The chemical equation for this reaction is balanced, and the conclusion is that BaO is neither soluble nor insoluble; it reacts with water.

What is the main question addressed in the video regarding barium oxide?

• Whether BaO is a metal or non-metal
