Answer 1

Answer:

CuO is a base because it reacts with acids to produce salt and water only.

The condition for a compound to be a base is that it must react with acids to form salt and water only.

Some bases which dissolve in water are called alkalis. Example : Sodium hydroxide, ammonium hydroxide.
