Investigating indigestion remedies

Greetings fellow Scientists!

In our recent session we were investigating which indigestion remedy was the most effective. We used the following equipment in this experiment:

We started by grinding the tables to increase the surface area:

The tablet was then dissolved in water. Lastly we added hydrochloric acid to resemble the conditions during indigestion. Litmus paper was used to check the pH at the start (once the acid was added) and after 5 minutes to check how effective the lablet was at neutralising it.

We found out that Rennie was the best at neutralising excess acid.
