| Physical Description | Copper chloride appears as a yellowish-brown powder (the anhydrous form) or a green crystalline solid (the dihydrate). Noncombustible but hydrogen chloride gas may form when heated in a fire. Corrosive to aluminum. Used to manufacture other chemicals, in dyeing, in printing, in fungicides, as a wood preservative.Cupric chloride and ammonia contains various concentrations of cupric chloride in ammonium hydroxide. This forms a copper ammonia complex. It is corrosive to skin, eyes, mucous membranes and metal. This material is used to etch copper from printed circuit boards.LiquidWet SolidDry PowderLarge CrystalsOther SolidYellow to brown deliquescent solidForms dihydrate in moist airSoluble in water[Merck Index] Yellow-brown powder[MSDSonline] |
