Question

What is the pOH of a solution that has a hydronium ion concentration [H3O+] of 8.26 x 10–5 M?

1.20 x 10 ^-10


4.08


-9.92


9.92


-1.20 x 10 ^-10


-4.08

Answer 1

9.92

Step-by-step explanation:

Since we are given the concetration of H+ we can find the ph by taking the negative log and then subtracting the ph from 14 to give us pOH

-log(8.26e-5) = pH= 4.08

pOH= 14-4.08

pOH= 9.92
