Explanation:
Lime is an oxide of calcium(CaO). As a metallic oxide, it produces a basic solution when it reacts with water.
- The main reason why lime is added to lakes is to reduce acidity in the lake water.
Bottom muds in lakes are usually acidic and makes the water hypertonic. When lime is added, it reduces the pH of the water and causes acidity to reduce.
