What is the PH of a Solution with a [H+]=1X10-7

Question

What is the pH of a solution with a [H+]=1X10-7 mol/L?
A) 2
B) 7.4
C) 6
D) 7
E) 8.2

Accepted Answer

The pH of a solution is calculated using the formula pH = -log[H+]. In this case, [H+] = 1X10-7 mol/L, so pH = -log(1X10-7) = 7. Therefore, the answer is D, pH = 7.
