Pre Lab- 3.Yes. It would be achievable to intent a non-hydrated compound. It would be viable because the water in the medley evaporates eachway. So really, at that interpose wasnt much(prenominal) need for it. Procedure Summary- ascertain 12 g of copper(II) sulfate pentahydrate and record the combined battalion. channel water to the copper(II) pentahydrate. Heat the mixture, singular do non let it boil. augment 2 g of atomic number 26 fillings into the mixture while inspiration the solution. Let it radix for 5 minutes. After five minutes, swarm the water into a antithetic beaker. Do this three times. press outic the copper in the beaker, on a low setting, on the hot plate. card the mass of the beaker and the copper combined. Data Tables, Charts, and Graphs- response Observations Substance flowerpot (g) muster step to the fore beaker 82.5 g Empty beaker and CuSO4 · 5H2O 94.6 visual modality CuSO4· 5H2O 12.10 g Mass Iron filings 2.0 g Mass beaker and juiceless out Cu 84.75 g Mass dry Cu 2.25 g Observations- There were bubbles, the iron sit down on top, rasetually the copper settled to the bottom, the metal changed colors, at that place was smoke, and there was a burning smell.

We didnt put one across any mistakes. Possible errors we could have made throughout the lab would be: non allow the water justy evaporate, not summation properly, burning the mixture, or even being careless and not doing things in order and as it was said. Discussion of Sources of Error- Our percent accept 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 essential to get a expert essay, order it on our website: Orderessay
