Explain why copper oxide is considered a base, even though it doesn't dissolve in water to form an alkali.
Explain why copper oxide is considered a base, even though it doesn't dissolve in water to form an alkali.
Copper oxide is considered a base because it can react with acids and neutralize them, even though it is insoluble in water.

Study Notes
- Copper reacts with oxygen when heated strongly in air, resulting in the formation of black powder copper oxide.
- Metal oxides are called bases.
- A base neutralizes acids through chemical reactions.
- Metal oxides like sodium and calcium oxide dissolve in water to form alkalis, thereby acting as bases.
- Copper oxide, a metal oxide, does not dissolve in water
- Copper oxides still react with acids and neutralize them.
- Copper oxide reacts with sulfuric acid to produce copper sulfate and water.
Reaction of non-metals with oxygen
- Non-metals react with oxygen to form oxides.
- Most oxides of non-metals are water-soluble
- Oxides of non-metals dissolve in water to produce acids.
- Sulfur, a non-metallic element, is a yellow crystalline solid.
