Sarah Kovach October 31, 2018 Experiment IV In this experiment I used titrated different types of solutions to find the molarity, deviations, and percent of carbonate. In part II I found the volume of base to acid ratio and ended up with an average relative deviation of 8.53ppt. In Part III I used the mass of Oxalic acid and used the values calculated from titration to determine an average relative deviation of 8.14ppt.In part V I used the mass of an unknown solid acid to determine the average relative deviation of 11.70ppt. In part VI I used the unknown salt to determine the percent carbonate that was used, which I found to be 4.4 %. Error could easily occur by going past the end point in the titrations used. I believe most of my experiments were off because of this reason. There can also be error by misreading the burette and even the weight of the mass on the scale. When calculating the molarity, it is very important to have results that are similar to have a close deviation. When the deviation is very different from the others then the average relative deviation will be too large compared to the mean value resulting in an out of the range answer for this experiment.
