Copper(II) chloride - Wikipedia, the free encyclopedia
Copper(II) chloride is the chemical compound with the formula CuCl 2 . This is a yellow-brown solid which slowly absorbs moisture to form a blue-green dihydrate. Anhydrous CuCl 2 adopts a distort...

Cupric Chloride is also called Copper Chloride and is soluble in water and alcohol. Uses include photography, electroplating baths, fungicides, pigment for glass and ceramics, mordant in dyeing and printing fabrics. ... IMPORTANT! Shipping is restricted. Cupric Chloride is hazardous and cannot be put on an airplane.

This is the reason why cupric chloride is one of two main etchants widely used by PCB fabricators. The primary advantages of cupric chloride in a hobbyist prospective is that a maintained solution never becomes exhausted.

Cupric chloride etchant must have at least some detectable free acid in it for optimum etch efficiency. Hydrochloric acid keeps the relatively insoluble cuprous chloride (CuCl) molecule in solution where it can be regenerated and also removes any traces of copper oxide from the surface of the copper metal being etched.
