We add A g Cucl2•2H2O to a beaker with B ml of ethylene glycol. Then stir the solution up and heat to C ℃. The green solution is obtained. Following this, dissolving Eg thiourea in F ml of ethylene glycol makes solution J. Adding solution J to solution D, we heat it, stirring it simultaneously. Then it leads to the separation of white flocculent precipitate in solution, which becomes milky liquid soon. At last, we obtain the yellowish mixture. |
