Unformatted text preview: In part 2 of this experiment we did the titration of the product of the reaction of calcium in water. We did this in order to determine the molecular formula of calcium hydroxide through experimentation. We did this by doing two trials of the same experiment in which we added calcium and .1% thymol blue indicator to water then added .30M HCl until the solution turned yellow to indicate an acidic solution. We then used the data to determine moles of OH and calcium used then used this to find the ratio between the two and determine the experimental molecular formula. Possible sources of error could have arisen from the calcium having oxidized, having added too much or too little of the HCl acid, and from having taken incorrect measurements....
