- The wastes of many factories contain acids. If they are allowed to flow into the water bodies, the acids will kill fish and other organisms. The factory wastes are, therefore, neutralised by adding basic substances.
- Our stomach contains hydrochloric acid. It helps us to digest food. But too much acid in the stomach causes indigestion, which is painful. To relieve indigestion, we take an antacid such as milk of magnesia, which contains magnesium hydroxide. It neutralises the effect of excessive acid.
- When an ant bites, it injects the acidic liquid (formic acid) into the skin. The effect of the acid can be neutralised by rubbing moist baking soda (sodium hydrogen carbonate) or calamine solution, which contains zinc carbonate.

Assertion 1: The waste of many factories contain acids; therefore, they are neutralised by adding basic substances before they are allowed to flow into the water bodies.
Explanation: Factories often produce waste that contains acidic substances. If this waste is directly discharged into water bodies without neutralization, it can harm aquatic life and disrupt the balance of the ecosystem. To prevent this, factories neutralize the acidic waste by adding basic substances. This neutralization process involves a chemical reaction between the acid and the base, resulting in the formation of a salt and water. The addition of a base helps to raise the pH level and make the waste less harmful to the environment.
Assertion 2: Magnesium hydroxide neutralizes the effect of excessive acid in the stomach.
Explanation: Excessive acid in the stomach can lead to conditions like acid reflux, heartburn, and gastric ulcers. To alleviate these symptoms, medications containing magnesium hydroxide are often used. Magnesium hydroxide acts as an antacid by neutralizing the excess stomach acid. It reacts with the acid to form magnesium chloride and water, reducing the acidity and providing relief from the discomfort caused by excessive stomach acid.
Assertion 3: The effect of the acid injected into the skin through an ant bite can be neutralized by rubbing moist baking soda (sodium hydrogen carbonate) or calamine solution.
Explanation: When an ant bites, it injects formic acid into the skin, which can cause pain, itching, and inflammation. To neutralize the effect of the acid, moist baking soda (sodium hydrogen carbonate) or calamine solution can be applied to the affected area. Baking soda is a basic substance that can react with the acid, forming water and a salt. This reaction helps to neutralize the acidity and provide relief from the symptoms caused by the ant bite.
Conclusion: All three assertions are correct. Neutralization is a common process used in everyday life to counter the harmful effects of acids. It is essential for environmental protection, treating stomach acidity, and relieving discomfort caused by acid reactions on the skin.
