What is the ph of the solution in which the h + is 1.0 x10-4 mol/l

A. 14.00

B. 10.00

C. 4.00

D. 1.00

The definition and formula to calculate pH is:

pH = log { 1 / [H+] }

So, the pH of this solution, whose molar concentration of H + is [H+] = 1.0 * 10^-4, is:

pH = log { 1 / (1.0 * 10 ^-4) } = log (10^4) = 4

Answer: option C. 4.00
