what is the pH of a solution if the [H3O+] is 6.7*10-4m?

You need 5 basic conversions (some give you a 6th, but all you need are these 5):

1) pH = –log [H+] (negative log of the concentration of the hydronium ion) thus,
2) [H+] = 10 ^ -pH.
3) pOH = –log [OH-] and thus,
4) [OH-] = 10 ^ -pOH
5) pH + pOH = 14

The pH of a solution if the [H3O+] is 6.7×10-4m is 3.14.

Given concentration of H+ = 6.7×10-4m

The pH = -log[H+]

pH = -log6.7×10-4

pH = 3.14

What pH represents?

The pH of the solution represents the acidic strength of the solution.

If the value of pH between 2 to 4 consider as strong acid and pH value more than 5 consider as weak acid.
