pH of acid rain is below
(A) 5.6
(B)6
(C)6.5
(D)7

Assertion (A) : The pH of acid rain is less than 5.6. Reason (R) : Carbon dioxide present in the atmosphere dissolves in rain water and forms carbonic acid.

Assertion: The pH of aicd rain is less than 5.6 Reason: Carbon dioxide present in the atmosphere dissolves in rain water and forms carbonic acid.

Given below are two statements : Statement I : The pH of rain water is normally 5.6. Statement II : If the pH of rain water drops below 5.6, it is called acid rain. In the light of the above statements, choose the correct answer from the options given below:

The arithmetic mean of first 11 natural numbers is (a) 5 (b) 5.5 (c) 6.0 (d) 6.5

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. Why does the rain water normally have a pH of about 5.6 ?

From where do these acids come in acid rain ?

The additive inverse of (-6)/(-5) is: (a) 5/(-6) (b) 6/5 (c) (-6)/5 (d) (-5)/6
