Antacids lab

The NaOH solution's concentration is about 0. Products of the experimental reactions could be harmful to the environment, and thus should be disposed of accordingly. A drop or two of indicator called bromthymol blue BTB is all that is needed to observe the endpoint.

Titration of an antacid answers

The goal is to get a feel for the buret. The amount of acid neutralized by the antacid can then be determined by subtracting the amount neutralized by the titrated base from the total amount of acid neutralized. Proper attire approved lab goggles, appropriate clothing, closed-toed shoes should be worn at all times. You can warm the water to aid the dissolution if needed. Hill 2 Introduction This purpose of this lab is to test and compare the ability of a few common commercial antacids to neutralize hydrochloric acid stomach acid. Results Part 1. The molar mass of KHP is The solution was then titrated with hydrochloric acid until the indicator produced a distinctive green color. Clean your bench top and rinse your glassware. Procedure 1 Follow the procedure outlined for buret usage.

Procedure 1 Follow the procedure outlined for buret usage. The goal is to get a feel for the buret. MOH— individually and average with error. In addition to the dose effectiveness of each antacid in the study, the cost effectiveness was also determined. Hill 5. Clean your bench top and rinse your glassware.

In this lab, both forward direct and back indirect titration methods are used to ascertain the strength of the antacid.

back titration of antacid tablets calculations

Considering this, the cost effectiveness of the antacid is more important than the per dose effectiveness, at least as far as the consumer is concerned.

Find the volume of water added by difference. The neutralization capabilities of all three were evaluated using back titration.
