Introduction

The reason why we chose this experiment is because we are very familiar with the topic on neutralization since we have been studying it for a few years. So, we have more confidence in dealing the problems that might occur when we perform the experiment. Although we seldom use anti-acid tablets to relieve our stomachache, it is still a very good opportunity to know more about these drugs.

As we all know, Hong Kong people are usually under stress, having stomachache is thus very common. Under a plethora of anti-acid tablet brands available in the market, it is really difficult for us to choose the best buy. Therefore, we would like to investigate which brands of anti-acid tablets could help the most. We plan to spread our results to our friends and relatives so that they could not only save money, but also have their stomachache relieved immediately.

We have chosen 4 brands of anti-acid tablets which mainly contain Mg(OH)2 and Al(OH)3 as their active ingredients. They are among the most commonly used brands in Hong Kong. We hope by performing our experiments, we could find out the most economical and effective anti-acid tablets.

Calculations

Magsil tablet in milk

Mean titre = 15.60 + 15.65 + 15.60

3

= 15.62 cm3

No. of mol of OH- reacted = MV

= 0.1 x 15.62

= 1.562

No. of mol of H+ = 1.562
