The video introduces an experiment that shows how drugs work. Let's write a report on the expected results of the experiment and what you have learned from watching the video.
If you burp without eating or have a stomach ache, it may be because your stomach produces more acid ( stomach acid) than usual and the acidity of gastric juice is stronger than usual. In such cases, there are medicines that use chemical reactions to reduce the acidity of gastric juice and relieve heartburn and pain.
The pH test paper has turned from red to green.
When baking soda, a neutralizer of stomach acid, was added to an aqueous solution of hydrochloric acid, which was used to simulate gastric juice, and placed on pH test paper, the color of the solution changed. This is an alkaline drug that counteracts the acidity of stomach acid, causing a chemical reaction that makes the gastric juice closer to neutral. The reason for this is that the chemical reaction produces carbon dioxide gas (CO2), but you do not feel this reaction yourself. However, this reaction in the body makes the inside of the stomach neutral, which relieves heartburn and stomach pain.
