Question

What is the OH- concentration for a solution with a pOH = 0.918? a) What is the OH-? b) What type of solution is this (acid, base, or neutral)?

Answer 1

Answer #1

we have
pOH =-log[OH-]

so [OH-] = 10^-log[OH-]
= 0.121 M
******
pH = 14 - pOH = 14 - 0.918
= 13.082

Since pH ids greater than 7 ,

The solution is a base
