A springly soluble copper(II)-tartrate, CuC₄H₄O₆ has been prepared. It behaves as a mono-­basic add in aqueous solution due to the reaction,

                                                CuC₄H₄O₆ + H₂O \(\rightleftharpoons\)CuC₄H₄O₆\((\bar{OH})\)+H⁺

for which the equilibrium constant is 2.57 x10^-6. The water soluble sodium, potassium and ammonium compounds of composition M Cu C₄H₄O₆(OH) or M Cu C₄H₃O₆.H₂O have also been prepared.
