Answer
- Indigestion is due to the production of excess hydrochloric acid in the stomach caused due to over eating. Since it is the formation of acid the pH should be less than 7.
- Antacid solution is a base so definitely the pH will be greater than 7 and used to treat people facing acidity
- Antacids are used to treat the excess acid formed in our stomach due to Antacids are bases that neutralises the acid inside the stomach and prevent from pain and discomfort.
- Magnesium hydroxide and sodium hydrogen carbonate are two antacids
