               Alkalinity to phenolphthalein Nil
               Cu₃        Nil
     Greater part of white coating is insoluble in 

     water & in con HCl. (In one case boil/<nd>ed 

     lid with strong Na₂Cu₃ solution – result 

     negative)

     of this show a special white efflorescence. This 

     is alkaline to litmus & contains NaCl + SO₃
