Question

What is the poh of a solution that has a oh- concentration equal to?

Answer 1

Answer

Sandy,

Remember the formula:

POH = -log [OHA]

We are given the concentration of OH-

pOH = - log (9.7 x 10-11)

pOH = - (-10.)

pOH = 10.

Hope this helps!

Answer 2

Explanation:

where [OH−] is the hydroxide ion concentration of the solution in M or mol⋅dm−3 , moles per cubic decimeter, or equivalently moles per liter. Substituting [OH−]=1.36⋅10−10 mol⋅dm−3 , pOH=9.866 .
