Thermal Decomposition of Copper(II) Carbonate
CuCO3 → CuO + CO2
概述
Green copper(II) carbonate decomposes when heated to form black copper(II) oxide and carbon dioxide gas. This is a classic laboratory demonstration showing the color change from green to black. The reaction occurs at relatively low temperatures (~290 C).
