Copper carbonate/Cupric carbonate basic (MF: CO3.Cu.CuH2O2 MW:221.11), is a peacock-green amorphous powder. It is stable at room temperature, insoluble in water and ethanol, soluble in dilute acids and ammonia water, and prone to decomposition at high temperatures. It is primarily used in industrial pigments, agricultural and forestry fungicides, feed additives, chemical intermediates, and electroplating and metallurgical additives.
