What is the ph of a solution with [h301+]= 5.0 × 10-5

1 answer

To calculate the pH of a solution with a hydrogen ion concentration of [H3O+] = 5.0 x 10^-5 M, you would use the formula:

pH = -log[H3O+]

Plugging in the given value:

pH = -log(5.0 x 10^-5)
= -log(5.0) + log(10^-5)
= -0.699 + 5
= 4.301

Therefore, the pH of the solution with a hydrogen ion concentration of [H3O+] = 5.0 x 10^-5 M is 4.301.
