Question

\( \text{CO}_2 \) goes to air, causes greenhouse effect and gets dissolved in water. What will be the effect on soil fertility and pH of the water?

• A. Increases
• B. Decreases
• C. Remain same
• D. None of these

Hint:

The increase in \( \text{CO}_2 \) leads to a decrease in soil fertility and a decrease in pH of water due to carbonic acid formation.

Answer 1

The Correct Option is B

Step 1: Greenhouse effect.
The increased levels of \( \text{CO}_2 \) in the atmosphere cause global warming and affect soil fertility. \( \text{CO}_2 \) dissolved in water forms carbonic acid, which lowers the pH of water, affecting aquatic life.
Thus, the correct answer is (2).
