Question

What is the concentration of hydroxide in a solution with a pOH of 9.8?

ph+pOH=14 [OH-]=10^-pOH

Answer 1

1.6 x 10⁻¹⁰ M

Step-by-step explanation:

The question already gives pOH, so you do not have to subtract from 14, as you would have to do if they gave you pH.

[OH-]=10^-pOH = 10⁻⁹.⁸ = 1.6 x 10⁻¹⁰ M
