cloud has a pH of 2.0

rainfall has a pH of 5.5
how many times more acidic has the moisture been in the clouds?

please help

The acidity of the rain is approximately 3000 times more. You can figures exactly by the following:

pH = - log(H^+)
2.0 = -log(H^+)
(H^+) = 1 x 10^-2 = 0.01

pH = 5.5. (H^+) = 3.16 x 10^-6

0.01/3.16E-6 = 3,164 times greater.
