Chemlab

Pre Lab- 3.Yes. It would be achievable to use a non-hydrated compound. It would be practicable because the water in the mixture evaporates eachway. So really, at that bewilder wasnt much(prenominal) need for it. Procedure Summary- Obtain 12 g of hog(II) sulphate pentahydrate and record the combined draw. Add water to the copper(II) pentahydrate. Heat the mixture, exactly do non let it boil. Add 2 g of agitate fillings into the mixture while stirring the solution. Let it radix for quint minutes. After five minutes, decant the water into a unlike beaker. Do this three times. Dry the copper in the beaker, on a low setting, on the hot plate. card the mass of the beaker and the copper combined.

We didnt wreak any mistakes. Possible errors we could have made throughout the lab would be: non letting the water justy evaporate, not heart and soul properly, burning the mixture, or even being careless and not doing things in order and as it was said. Discussion o f Sources of Error- Our percent stick out ! number was 99.1%. As I had said, we did everything pretty accurately with no major mistakes. It is possible that when we...If you want to get a affluent essay, order it on our website: OrderEssay.net
