Question

$C{O}_2$ goes to the air causes the greenhouse effect and gets dissolved in water. What will be the effect on soil fertility and $pH$ of the water?

• A. Increase
• B. Decrease
• C. Remain same
• D. None of these

Answer 1

The correct option is B Decrease

Carbon dioxide dissolves in water to form carbonic acid.
$H_{2}O+C{O}_2\to H_{2}C{O}_3$
Due to this $pH$ of the water will decrease (it will become more acidic) and soil fertility will decrease.
