Chemicals required:
cu-sulphate pentahydrate -2g
Thi-urea-2g
Procedure:
*2 g of thiourea crystals dissolved in 20 ml of hotwater in a round bottom flask and cooled to flask at room temperature.
*Solution of cu-sulphate is prepared by dissolving of 2g in 20ml water the flask is stoppered well and thoroughly aftereach addition of copper sulphate.
when the addition of copper sulphate solution is completely dissolved.
The flask is again shaken well for 20 minutes. At this stage cris complex will begin to appear.
The content of the flasks are heated for 5to 20 minutes .The flask is cooled to room temperature under ta water.
The another liquid is decamped off . The oily liquid of crystal formed at side of the flask are thoroughly with 2:1 of thiourea solution.
When white crystal is formed , Now the crystals are filtered at the pump, washed with distilled water and dry. the yield is recorded.
