Special Note: How to Make Copper(II) Chloride Substitute
Copper(II) chloride is quite expensive and a cheap substitute that works equally well is made as follows.

Thoroughly mix equal volumes of finely powdered (or finely crystalline) copper(II) sulphate and sodium chloride.

All reactions and observations will be identical to those made with copper(II) chloride, at one quarter the cost.
