Titration of Calcium HydroxideG

We did this by titrating Hydrochloric Acid into 10 com of calcium hydroxide. As we titrated HCI into the calcium hydroxide pop outcome, the phenolphthaleins pink shade given to the calcium hydrated oxide slowly became clearer until the complete omit of pink color in the antecedent of base and social disease. My honor of 1. 58 g/mol was close to the accepted value of . 59 g/mol with hardly a 0. 6 + 0. 007% misapprehension, which is almost similar to the theoretical value. Because of such(prenominal) a shrimpy percentage error, one can put the error to random error, and non overbearing because of its small value.Limitation/weakness How much did it need my result gay error exists raze outside doubt, where the HCI solution was possibly non correctly stirred along with the Calcium hydroxide. Because of the fact that this is a titration experiment, the stirring and total of hydrochloric acid and calcium hydroxide required to be constant in parliamentary procedure for the reaction and correct mount of hydrochloric acid was used to undermine the basic nerve of calcium hydroxide. Because of the inconsistent stirring, there must(prenominal) have been a small bar of error attributed to this limitation, though it whitethorn not look as much.Possibility The Calcium Hydroxide solid that did not dissolve into the pee whitethorn have passed the filter into the real solution used, causing discrepancies in the data. A second limitation/weakness that may have caused our error is because of the fact that we may not have been careful bountiful with the filtration of the saturated Calcium Hydroxide. Because the filters themselves may not have been perfect experiment tycoon have taken a vilify turn with solid Calcium Hydroxide within the solution as well, needing a smidgen more Hydrochloric Acid to pine away it.Evaluation of quality of the result Although there is limitations to our measuring, since we were barely subject to measure to 2 decimals as a volume, this experiment is still a valid way to figure out the concentration of Calcium Hydroxide with fairish the amount and concentration of Hydrochloric Acid, and can be used by other scientists who would theoretically have no idea roughly how to go about the method of find the concentration of Calcium Hydroxide. Limitation or weakness Improvement 1 . Human error exists even outside disbelief, where the HCI solution was possibly not correctly stirred along with the Calcium Hydroxide.To lower this error and improve this limitation, we could have the same psyche stir the solution/titration constantly, with more clearcutness and concentration over this mixture, as to loaf the correct amount of HCI needed to neutralize the solution without any disagreements over what modify means or not. With two people concentrated over specific tasks, the uncertainty would also become much small as well due to slight error attributed to our mistakes. 2. Possibility The Calcium Hydroxi de old that did not dissolve into the pissing may have passed the filter into the true(a) solution used, causing discrepancies in the data.One of the biggest improvements we could cod is that we could, this time around, not add such a large amount of Calcium Hydroxide powder into irrigate blindly, as had been done before, so that we would be able to have more saturated water to make with, as opposed to what we had to work with at that moment when the experiment was done. By doing that, we would be able to reduce uncertainty that may have come along with the solid Calcium Hydroxide mix in with the saturated solution.
