This experiment aimed to determine the effectiveness of acid neutralizing antacid using different types of antacids. Antacids were basically used to neutralize acid in a very short period of time. It is mainly used to relieve heartburn by neutralizing acids as soon as they reach the body. Heartburn was a form of indigestion felt as a burning sensation in the chest, caused by acid regurgitation. This is a very offensive condition that can be very painful. A person suffering from heartburn feels it as if they are having a heart attack. This normally happens when hydrochloric acid from the stomach escapes into the esophagus. Say no to plagiarism.

There were different types of antacids containing different ingredients like calcium carbonate, magnesium hydroxide, aluminum hydroxide and/or sodium bicarbonate. Popular brands of antacids containing the above ingredients are: Alka-Seltzer. Milk of Magnesia. Alternagel, Amphojel. Gaviscon, Gelusil, Maalox, Mylanta, Rolaids. Pepto-Bismol. Bellies. The antacids that were used in the experiment and the compositions are: Image Compositions per tablet 680 mg of calcium carbonate 80 mg of magnesium carbonate 250 mg of sodium alginate 133.5 mg of sodium bicarbonate 80 mg of carbonate calcium 400 mg dried aluminum hydroxide 400 mg magnesium hydroxide 40 mg simethicone 324 mg aspirin In most antacids, calcium carbonate was the active ingredient because it was an antacid powerful and fast-acting. Objective: To know the effectiveness of antacid neutralizes acid using different types of acids Materials and method: Equipment required: Water 100 ml Beakers 0.1 M Hydrochloric acid Universal indicator Universal indicator card Weigher Different types of antacids ( tablets) Stirring rod Method: 1 g of Rennie was crushed and placed in the beaker. Then, 10 ml of water, 16 drops of universal indicator were dropped into the beaker and the mixture was mixed with the stirring rod. The color observed in the experiment after stirring was light green with a pH of 7. Then, 1 drop of 0.1 M hydrochloric acid was added uniformly until the mixture turned into acid. The same process was repeated for Mylanta, Gaviscon, Alka-seltzer. The pH value was 8 for Mylanta, 7 for Gaviscon and 6 for Alka-seltzer when a mixture of 10 ml of water and 16 drops of universal indicator was shaken. Safety Precautions: The experiment was carried out on a laboratory bench. Eye protection goggles were worn by everyone performing an experiment to protect against eye burns or eye injuries. Hydrochloric acid was not touched by anyone during the experiment. The body should be cleansed with fluid if acid is spilled anywhere in the body. Results: Figure 1. In Figure 1, we can see that: For 0 drops of HCl, the pH value of Mylanta was 8, which was basic while other antacids are not. basic for zero drops, which makes experimenters think that Mylanta was so effective for heartburn. But Mylanta did not maintain its pH value as there was a drastic decrease from 8 to 4.5 in 5 drops which was so acidic while other antacids maintain its pH value mainly Gaviscon and Alka- Seltzer.
