When concentrated ammonia solution (ammonium hydroxide) is added to a clear, light blue, aqueous solution of copper(II) chloride, a powdery, light blue precipitate of copper(II) hydroxide forms. Further addition of ammonia causes the copper ion to go back into solution as a deep blue ammonia complex
