The mineral of the formula Cu (OH) 2 is called spertiniite. Copper (II) hydroxide is rarely found as an uncombined mineral because it slowly reacts with carbon dioxide from the atmosphere to form a basic copper (II) carbonate. Thus copper slowly acquires a dull green coating in moist air by the reaction: See more Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH)2.
