    In aqueous solution, copper(II) exists as [Cu(H 2 O) 6] 2+. This complex exhibits the fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex. Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide. A simplified equation is:

    en.wikipedia.org/wiki/Chevreul's_salt

    Chevreul's salt is prepared by treating aqueous copper(II) sulfate with a solution of potassium metabisulfite. The solution changes colour from blue to green immediately. The identity of the green species is unknown. Heating this solution produces a reddish solid precipitate: 3 CuSO 4 + 4 K 2 S 2 O 5 + 3 H 2 O → Cu 3 (SO 3) 2 •2H 2 O + 4 K ...

    en.wikipedia.org/wiki/Copper_hydride

    Copper hydride is an inorganic compound with the chemical formula CuH n where n ~ 0.95. [3] It is a red solid, rarely isolated as a pure composition, that decomposes to the elements. [ 4 ] Copper hydride is mainly produced as a reducing agent in organic synthesis and as a precursor to various catalysts.
