Copper oxide<span> is a base because it will react with acids and neutralise them, but it is</span>not<span> an alkali because it </span>does not dissolve in water. Sodium hydroxide is a base because it will react with acids and neutralise them. It's also an alkali because itdissolves in water<span>.</span>
