Aim The purpose of this experiment is to determine the percentage by mass of calcium carbonate in eggshells. Introduction To avoid the breakage of eggs before reaching market‚ the eggshells needs to be as strong as possible. The strength of eggshells is mainly determined by the percentage of calcium carbonate in it. In order to monitor the quality of eggshells‚ the following experiment has to be done to determine the percentage of calcium carbonate in eggshells. In this experiment‚ back titration
