Cupric chloride, in its anhydrous form, appears as a yellowish-brown powder whereas in its dihydrate form it appears as a green crystalline solid. Step 2: Solve the given statements NaCN (aq)+CuCl (aq)NaCl (aq)+CuCN (s)NaCN (aq)+CuCl (aq)NaCl (aq)+CuCN (s) 2Na (s)+Cl2 (g)2NaCl (s) Na (s)+CuCl (aq)NaCl (aq)+Cu (s) The first reaction involves the oxidation of sodium and the reduction of chlorine. Copper can also have oxidation numbers of +3 and +4. The second reaction involves the oxidation of sodium and the reduction of copper. Only concentrations below five ppm are allowed in drinking water by the US Environmental Protection Agency. It is also commercially practical to combine copper(II) oxide with an excess of ammonium chloride at similar temperatures, producing copper chloride, ammonia, and water:[citation needed]. PbNO3 3. Copper (II) chloride has also been studied as a harmful environmental pollutant. Oxidation numbers are positive or negative numbers, but dont confuse them with positive or negative charges on ions or valences.\r\n\r\nOxidation numbers are assigned to elements using these rules:\r\n

    Rule 1: The oxidation number of an element in its free (uncombined) state is zero for example, Al(s) or Zn(s).
