For this reason the experiment could not be completely accurate. This however could also lead crystals being lost from the crucible during the stirring. There were many factors that may have affected the results of the experiment.
The overheating of the copper II sulphate could also have a detrimental effect on the results, as this would lead to the production of copper oxide and the crystals would have less mass. Procedure First a lid was chosen so the water could not get back into the crucible.
One way is that it produced a brown-colored carbon build up on the crucible, altering the mass data higher than it should have been. We can see that some experimental errors have occurred along the way. The crucible was then carried to the scale and measured again when the end of the period got close.
By weighing the crucible empty and by weighing it again once the Copper Sulfate is added, the difference of these 2 amounts would mathematically express amount of Copper Sulfate in the crucible.
Discussion As with all experiments that we carry out, we have to expect some experimental errors. An oven was not available for the lab, so a Bunsen burner was used in its place. The crucible was then set in place a few inches up from the top of the Bunsen burner.
This can be proved by the color of the Copper Sulfate Pentahydrate, which after heating, did not turn to a fully white color. With the final mass measurement, the amount of water that evaporated was found, and with that, the percentage of water in Copper Sulfate Pentahydrate was found.
The mass was weighed to find the difference before and after heating. It could also be concluded that the copper II sulphate are blue in colour because of the water of crystallisation. The Bunsen burner may have also heated the Copper Sulfate unevenly, which may not have evaporated all the water, affecting the percentage to a lower number than it should have been.
It was also left to the eye of a human to acknowledge if the hydrated copper sulphate had turned white from blue. Bellow right is a desiccator. The free Chemistry research paper Percent Composition of Water in Copper SUlfate Pentahydrate Lab Report Version essay presented on this page should not be viewed as a sample of our on-line writing service.
This could not only be down to the under heating of the copper II sulphate but also that the fact that the substance becomes amorphous. The crucible then weighed again, so that the mass of the Copper Sulfate could be found. Copper Sulfate was heated in a crucible to evaporate the water.
By comparing these masses, the percentage of water was found. Agitation of the crystals inside the crucible while heating, could allow for more accurate results due to the crystals on the inside being moved allowed closer to the outside, at the hottest point.
