Question
Greetings, I need some major help as I have been going back and forth about how to interpret my results for this antacid lab. I’m not sure if my hypothesis is correct as I determined out of the 6 different calcium carbonate antacids that Tums was the most effective and thus it’s the best antacid from the selection of 6. Please someone help me verify this, I included the lab manual page and my results with a graph and data table. Please help me determine “the best” antacid from these. Antacid information is included in the photos. Note data table is class average data of two trials.

Antacids vary in their chemical makeup but they are all bases that neutralize stomach acid and raise pH re they all the same? You'll determine that as a class. Obtain one of the brands of antacid (make sure to try and test one that another group has not already selected if possible). Crush the antacid with a mortar and pestle and weigh out 1g of the antacid. Using an Erlenmeyer flask, dissolve the antacid powder in 40ml of DI water. Slide a stir bar into the flask and slowly turn the stir plate knob on until you have a gentle stirring motion. 1. 2. 3. Add 20 drops of Methyl Red to the flask as it is stirring. 4. Add drops one at a time of 1M HCl to the flask. Go slow and try to obtain consistent drop sizes. 5. When the flask turns a light pink/red for 30 seconds you are at the endpoint. All the base (antacid) has been exhausted by the HCl. 6. Record this number in Table 3 7. Repeat this procedure a second time and take the average of the two to report to the class
Explanation / Answer
Antacid is a substance that counteracts the action of acids. Antacids are used to get relief from symptoms like heart burn and indigestion.
The effectiveness of antacid depends on two factors.
Here, among the six given commercially available antacid brands, Medifirst required 227 drops of 1.0 M HCL to reach end point which is the highest. Therefore, the best antacid from the given list is Medifirst.
