Assertion : pH of rainy water is around 5.6. Reason : Water reacts with CO_2 in atmosphere and produce H^+.

Answer»

Both ASSERTION and Reason are correct and the reason is the correct explanation for assertion.
Both assertion and reason are correct, but the reason is not correct explanation of assertion.
Both the assertion and reason are incorrect.
The assertion is incorrect but the reason is correct.

Solution :`H_2 CO_3` (carbonic ACID) is produced by REACTION of `CO_2` with water. Which is decomposed to FORMED `H^+` , due to that water become acidic. Thus its pH VALUE is around 5.6.
