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

  • chemistry -

    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.
