Unformatted text preview: carbonate precipitating back out of its soluble form. This wasted calcium carbonate and was not cost efficient for the task. Fortunately acetic acid was then tested and gave much more desirable results. Acetic acid completely dissolved the calcium carbonate while keeping the resulting pH at 5. This meant no sodium hydroxide needed to be added to the solution and all of the calcium carbonate could be used for the supplement creating a far superior cost effective product and thus the right acid had been found for the job. The calcium concentration is .4032 M. We added 25.2 mL of hydrochloric acid....
