Transcript of Antacid Lab. Take the initial reading of the 0.1M NaOH in the buret. Add two drops of the methyl orange indicator. Slowly add in drops of NaOH to the HCl solution until the solution is tipping between orange and yellow. Record the end reading of NaOH on the buret. Repeat with the other two tablets. Do three more trials.

In part A of this experiment, the concentration of NaOH (aq) was determined. The calculated value of the base can then be used in the “back-titration” of another reagent as is done in part B where an antacid, composed mainly of CaCO 3(s) , is used to neutralize the acidic HCl (aq) solution.

Note: The Antacid Rocket Experiment used to be called the Film Canister Rockets, but with digital cameras taking over the market, it’s become harder and harder to find empty film canisters. If you can film canisters, that’s great, but this experiment recommends you use mini M&M tubular containers or clean, empty glue stick containers instead.

Prepare the standardized NaOH(aq) solution in a 50.0 mL buret just as in Part A and fill 3 separate Erlenmeyer flasks with a new solution of 25 mL 0.50 M HCl(aq), DI water, and a crushed antacid tablet with a total volume less than 75 mL. Heat the analyte solution for 5 minutes to finalize the HCl(aq)/ CaCO3(s) reaction.

Antacid Analysis Lab. Purpose of the Experiment. To determine the effectiveness. of antacid tablets. H. H. H. H. O. O. Dissociation of Water. 2 H2O <-> H3O+ +.

The aim of this laboratory experiment is to quantify the amount of HCl neutralized by two different antacids. The active pharmaceutical ingredients (APIs) in antacids work by either raising the pH and/or by buffering the solution so it is resistant to further pH change. This lab will deal with antacids that work through Figure 1.
