What is the [H3O+] for a solution at 25°C that has pOH = 5.640? A. 2.34 x 10-4 M B. 2.29 x 10-6 M C. 4.37 x 10-9 M D. 4.27 x

Answer 1

Answer #1

Given pOH= 5.640

We know that pH+pOH=14

So pH = 14-pOH

= 14- 5.640

= 8.360

We know that pH= - log[H3O+]=8.360

[H3O+]=10^-8.360

= 4.37*10^-9 M

Therefore option C is correct.
