Explanation:
Detailed explanation-1: -Malachite is an ore of copper. The formula of malachite is CuCO3⋅Cu(OH)2 C u C O 3 ⋅ C u ( O H ) 2 . Malachite reacts as though it is a mixture of copper(II) carbonate and copper(II) hydroxide. A small sample of malachite is added to excess dilute hydrochloric acid, HCl(aq).
Detailed explanation-2: -Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide. It is an ionic compound (a salt) consisting of the ions copper(II) Cu2+, carbonate CO2−3, and hydroxide OH−. The name most commonly refers to the compound with formula Cu2CO3(OH)2.
Detailed explanation-3: -CuCO3 · Cu(OH)2 is also known as Malachite (green).
