In this lab, two different titrations were performed with three different antacids to determine which brand is the most effective at the cheapest price. The antacids were ground up separately and approximately 0.2 grams of it was placed in a flask. Methyl Orange, an indicator, and a stir bar were added into the flask. The flask was then put on a stir plate which was under a buret with 0.1M hydrochloric acid. The acid was poured into the flask until there was a permanent pink colour.

It was found that the average amount of calcium carbonate in a Tums Regular Strength tablet was 520 milligrams which is 20 milligrams more than the amount claimed on the bottle. The Tums Ultra Strength was found to contain an average of 1130 milligrams of calcium carbonate in a tablet, which means that it contains 130 milligrams more calcium carbonate than listed on the bottle. Lastly, it was found that the average amount of calcium carbonate in a tablet of the Life Brand antacids was 420 milligrams, which is 80 milligrams below the amount of calcium carbonate claimed on the bottle. It was calculated that the Tums Regular Strength costs 3.7 cents per tablet, the Tums Ultra Strength costs 7.6 cents per tablet, and the Life Brand costs 3 cents per tablet. It was concluded that the most cost-effective bottle was the Tums Regular Strength due to it containing nearly the same amount of calcium carbonate listed on the bottle with a percent error of 4% while the other products contained higher percent errors. As well, the Tums Regular Strength tablet neutralized the second most amount of acid on
