Question

Calculate the pH of a solution that has a hydronium ion concentration, [H3O+], of 4.75×10−8 M.

pH= ?

Answer 1

pH=7.32

Step-by-step explanation:

pH is a mathematical expression that represents -log base 10 of the hydronium concentration:

`pH=-\log[H_3O]\\pH=-log(4.75x10^-8)\\pH=7.32`
