write an activity to show cupric chloride produce colour in flame​

Answer 1

✨ Answer ✨

Once prepared, a solution of CuCl2 may be purified by crystallization. A standard method takes the solution mixed in hot dilute hydrochloric acid, and causes the crystals to form by cooling in a CaCl2-ice bath. There are indirect and rarely used means of using copper ions in solution to form copper(II) chloride

Answer 2

Take a pinch of cupric chloride in a watch glass and make a paste with concentrated hydrochloric acid. Take this paste on a platinum loop and introduce it into a non-luminous flame. Cupric chloride produces a green colour flame.
