What Is the Solubility of Copper?


Quick Answer

The solubility of copper depends on the nature of the copper compound and the solvent used. In its metallic state, copper is soluble in nitric acid and sulphuric acid at a high temperature. Some copper salts are soluble in water.

The copper compounds that are soluble in water include copper chloride, chromite, formate, fluoride and gluconate. While compounds like copper acetate, bromide and oleate are soluble in alcohol, some copper (II) salts, such as copper carbonate and oxide, are insoluble in the same solvent. Some copper salts require ether, acidic or alkaline compounds in order to become soluble. Copper compounds that are soluble in alkaline solutions include copper ferrocyanide and copper nitrate.

The solubility of an ionic salt is dependent on the strength of the bond between the ions and the attractive force water has on the ions. The greater the force of attraction between the ions in the salt, the less soluble the salt is. The greater the effect of water on the ions in the ionic salt, the more soluble it is.
