The aim of this experiment was to investigate how different types of antacids neutralize acidic conditions and the speed at which they do so. Antacid tablets are commonly used to alleviate extreme acidity in the human digestive system, particularly in the stomach.
They work by lowering the pH of the stomach acid, correcting acidity. Two types of antacids, direct and remote, were examined in this experiment. Direct antacids target acidity in the stomach or other organs, while remote antacids slightly increase blood alkalinity to reduce acidity without affecting organs or cells.
Antacid tablets are widely used to treat extreme acidity in the human digestive system, primarily in the stomach. These tablets work by lowering the pH of stomach acid, effectively correcting acidity. Antacids are essential for individuals who experience upset stomachs after eating, as they neutralize acidic conditions by introducing alkaline properties. There are two main types of antacids: direct antacids, which target acidity directly in the stomach or other organs, and remote antacids, which slightly increase blood alkalinity without affecting organs or cells.
Antacids serve various purposes beyond human consumption.

They are used to neutralize acidic lakes to support animal and plant life, treat soils to facilitate crop growth, and even enhance the taste of certain foods. The distinction between acids and alkalines lies in their respective concentrations of hydrogen ions (H+) and hydroxide ions (OH-). This concentration determines the pH level, with higher concentrations of H+ ions indicating acidity and higher concentrations of OH- ions indicating alkalinity.
The neutralization process occurs as H+ and OH- ions combine to form water, a neutral substance.
The following equipment and materials were used in this experiment:
Based on preliminary results and prior knowledge, it is predicted that the antacid tablet "Rennie Relief" will neutralize the most hydrochloric acid due to its known effectiveness.
The experiment was conducted as follows:
Several parameters were established to maintain fairness and accuracy in the experiment:
For safety precautions, the following measures were taken:
The results of the experiment, showing the amount of hydrochloric acid neutralized by each type of antacid, are presented in the table below:
| Antacid | Tablet | 1st Test (cm3) | 2nd Test (cm3) | 3rd Test (cm3) | Average (cm3) |
|---|---|---|---|---|---|
| Bisodol | Tablet 1 | 62.7 | 55 | 52.9 | 56.9 |
| Tablet 2 | 65.2 | 59.8 | 54.3 | 59.8 | |
| Boots | Tablet 1 | 25.7 | 30 | 28.1 | 27.9 |
| Tablet 2 | 28.5 | 27.2 | 29.8 | 28.5 | |
| Boots Fruits | Tablet 1 | 42.4 | 40 | 38.5 | 40.3 |
| Tablet 2 | 44.8 | 39.6 | 43.2 | 42.5 | |
| Rennie Relief | Tablet 1 | 63.5 | 60.9 | 61.6 | 62 |
| Tablet 2 | 65.7 | 63.3 | 66.2 | 65.1 | |
| Settlers | Tablet 1 | 39.2 | 41.4 | 41.8 | 40.8 |
| Tablet 2 | 42.1 | 40.7 | 42.8 | 41.9 |
The results of the experiment indicate variations in the ability of different antacids to neutralize hydrochloric acid. The average amount of hydrochloric acid neutralized by each type of antacid is shown in the table above.
Among the antacids tested, "Rennie Relief" demonstrated the highest average neutralizing capability, with an average of 65.1 cm3 of hydrochloric acid neutralized. This result aligns with the initial prediction that Rennie Relief would be the most effective antacid.
On the other hand, "Boots" and "Boots Fruits" exhibited lower neutralizing capabilities, with average values of 28.5 cm3 and 42.5 cm3, respectively. These antacids proved to be less effective in neutralizing hydrochloric acid compared to Rennie Relief.
"Bisodol" and "Settlers" fell between the other antacids in terms of neutralization effectiveness. Bisodol had an average neutralizing capacity of 58.4 cm3, while Settlers averaged 41.35 cm3 of hydrochloric acid neutralized.
It is important to note that the differences in neutralization capability may be attributed to variations in the active ingredients and concentrations of antacids. The chemical reactions that occur when antacids react with hydrochloric acid may differ, leading to differences in the amount of acid neutralized.
Additionally, variations in tablet composition, such as the presence of fillers or binders, could impact the overall effectiveness of the antacid tablets. These factors should be considered when selecting an antacid for specific digestive conditions.
Further research could explore the specific chemical reactions between each antacid and hydrochloric acid to gain a deeper understanding of their neutralization mechanisms. Additionally, investigating the influence of tablet composition on neutralization effectiveness could provide valuable insights into antacid formulation and design.
The experiment aimed to assess the neutralizing capabilities of different antacid tablets on hydrochloric acid. The results showed that "Rennie Relief" exhibited the highest average neutralizing capability, followed by "Bisodol," "Settlers," "Boots Fruits," and "Boots."
These findings have implications for individuals seeking relief from acidic digestive conditions. It is important to choose an antacid that effectively neutralizes acid based on the specific condition and symptoms. "Rennie Relief" may be a suitable choice for individuals with severe acidity, while "Boots" and "Boots Fruits" may be less effective options.
Overall, the experiment contributes to our understanding of antacids and their varying effectiveness in neutralizing acid. It highlights the importance of considering the active ingredients and concentrations when selecting an antacid for digestive relief.
This experiment went quite well but as it was my first time doing this type of experiment I do not know if it went as the way that it should as in result wise, speed and overall evaluation of procedure. If I were to try this experiment again to improve it I would only use one personal source of hydrochloric acid and tablets so as to avoid any contamination which may explain my off key bisodol result. I would use titration in which to add my hydrochloric acid because this time I did not use titration but just measured some liquid out and poured it in but with titration it may be used for more than one experiment, make it quicker and a lot accurate. Finally if I were to do it again I would measure the amount of gas given off and also time the experiment to find out which is the quickest tablet to neutralise a certain amount of hydrochloric acid in a certain amount of time and with this I would be able to go on and prove which is the fastest acting tablet and why could it be because of actual make up of the tablet? (Mg or Ca) or just the concentration of the tablet itself.
Based on the results and findings of this experiment, the following recommendations are made:
