Explain why:
Factory waste is neutralised before disposing it into the water bodies.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Factory Waste**: Factory waste often contains acids, which can be harmful to the environment. These acids can come from various industrial processes and can significantly alter the pH of water bodies.

2. **Impact on Aquatic Life**: When acidic factory waste is disposed of directly into water bodies, it can lower the pH of the water. This change in pH can be detrimental to aquatic life, including fish, plants, and other organisms that rely on a stable pH for survival. Acidic conditions can lead to the death of these organisms and disrupt the entire ecosystem.

3. **Neutralization Process**: To prevent the harmful effects of acidic waste, it is necessary to neutralize it before disposal. This is typically done by adding basic (alkaline) chemicals to the waste. The basic chemicals react with the acids in the waste, resulting in a neutral solution.
