Question

Action of heat on Cu(OH)2

Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

As a result, hydroxide ion can displace water from the copper (II) ion, yielding copper hydroxide, Cu(OH)2, a blue precipitate. Heating copper hydroxide produces copper oxide, CuO, a black solid. Copper oxide dissolves in acid, regenerating the copper (II) ion, which once again binds to water.
