Copper phosphate
Encyclopedia
Copper phosphate is the salt of copper
and phosphoric acid
with the chemical formula
Cu3(PO4)2. Its color ranges from blue to green and is insoluble
in water.
Copper phosphate has a molecular weight of 380.581 g/mol.
It may be formed by the reaction of copper(II) oxide
, copper(II) hydroxide

with phosphoric acid
.
Copper
Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish...

Copper(II) hydroxide
Copper hydroxide is the hydroxide of the metal copper with the chemical formula of Cu2. Copper hydroxide is a pale blue, gelatinous solid. Some forms of copper hydroxide are sold as "stabilized" copper hydroxide, quite likely a mixture of copper carbonate and hydroxide...

Copper(II) carbonate
Copper carbonate is a blue-green compound forming part of the verdigris patina that is found on weathered brass, bronze, and copper. The colour can vary from bright blue to green, because there may be a mixture of both copper carbonate and basic copper carbonate in various stages of hydration...
