The acid concentration of a sample of acid rain with a pH of 4.20 would be  0.000063 M.

What is pH?

The pH of a substance is the degree of acidity or alkalinity of a substance. It is mathematically expressed as:

pH = - log [[tex]H^+[/tex]]

Where  [[tex]H^+[/tex]] is the hydrogen ion concentration or molarity of the solution.

In this case, the pH is 4.20. Substituting into the equation:

4.20 = - log  [[tex]H^+[/tex]]

log  [[tex]H^+[/tex]] = - 4.20

       [[tex]H^+[/tex]] = Antilog -4.20

                = 0.000063 M

Thus, the concentration of the sample acid rai with a pH of 4.20 would be 0.000063 M
