      Qualitative Analysis Question
      A green substance KK on heating gave off gas BB which turns lime water milky and a black residue CC was formed. When a black residue CC was dissolved in dilute Dulphuric acid,  blue solution DD was formed. When a pen-knife blade was dipped into the blue solution DD, a reddish brown coat was deposited on the pen-knife blade.
      (a) identify substances KK, BB, CC ans DD
      (b) write balanced chemical equation for each step outlined above
      (c). what would be observed when sodium hydroxide solution is added in small amount till in excess in a test tube containing little amount of substance KK?

      (i shall be grateful for you assistance.. am eagerly waiting for your responces) With regards
