This experiment aimed to find out how effective antacid was in neutralizing acid using different types of antacids. Antacids were basically used to neutralize the acid in a very short span of time. It is primarily used to relieve heartburn by neutralizing acids as they reach the body. Heartburn was the form of indigestion felt as a burning sensation in the chest, caused by acid regurgitation. It is a very offensive condition that can be very painful. Those who suffer from heartburn feel as if they are having a heart attack. It normally occurs when hydrochloric acid from the stomach leaks into the esophagus. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

There were several types of antacids with different ingredients such as calcium carbonate, magnesium hydroxide, aluminum hydroxide, and/or sodium bicarbonate. The most popular brands of antacids with the above ingredients are: Alka-Seltzer. Milk of magnesia. Alternagel, Amphojel. Gaviscon, Gelusil, Maalox, Mylanta, Rolaids. Pepto-Bismol. Tums. The antacids 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 calcium carbonate 400 mg of 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 a strong, fast-acting antacid. Purpose: To know how effective the antacid is in neutralizing acid using different types of acids Materials and method: Materials required: Water 100ml beakers 0.1M hydrochloric acid Universal indicator Universal indicator card Weighs Different types of antacids (tablets ) Stirring rod Method: 1 g of Rennie was crushed and dropped into the glass. Subsequently, 10 ml of water, 16 drops of universal indicator were dropped into the glass and the mixture was mixed with the stirrer. 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 was transformed 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 conducted on a laboratory bench Everyone who was performing an experiment kept protective eye goggles to protect themselves from burns or eye injuries. The hydrochloric acid was not touched by anyone during the experiment. The body should be cleansed with a liquid if acid is spilled in any part of the body Results: Figure 1. In Figure 1, it can be seen that: For 0 drops of HCl, the pH value of Mylanta was 8 which was basic while other antacids they are not basic for zero drops, which makes people who are doing experiments think that Mylanta was so effective against heartburn. But Mylanta did not maintain its ph value as there was a drastic decrease from 8 to 4.5 within 5 drops which was so acidic while other antacids maintain its ph value mainly Gaviscon and Alka-Seltzer. Rennie and Gaviscon are similar as their ph values ​​are the same in almost all cases. Since Mylanta is so acidic when it enters the body, it takes much longer to,.
