- Statement 1 is incorrect. The pH of the human body varies significantly depending on the location. Blood pH, which is often used as a measure of systemic pH balance, is slightly alkaline, typically tion. The general statement "pH of the human body is slightly acidic" is incorrect. - Statement 2 is correct. Indigestion, often felt as heartburn or acidity, is commonly caused by the production of excessive hydrochloric acid in the stomach. This excess acid can irritate the stomach lining and esophagus, causing pain and a burning sensation. - Statement 3 is correct. Milk of Magnesia is an aqueous suspension of magnesium hydroxide (Mg(OH)₂). Magnesium hydroxide is a weak base that acts as an antacid, neutralizing the excess stomach acid (HCl) according to the reaction: Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O. This neutralization helps relieve the symptoms of acidity.
Which of the following statements are correct? 1. pH of the human body is slightly acidic. 2. During the indigestion the stomach produces too much acid, which causes pain and irritation. 3. Milk of magnesia can be used to get rid of the excessive acidity.
