Problem: Determine the [OH-] concentration of a 0.741 M KOH solution at 25°C.

FREE Expert Solution

Any Group 1A metal when combined with OH-, H-, O2- or NH2- makes a strong base

K (Group 1A metal) is paired with OH-

KOHstrong base


Since KOH is a strong base, it will completely dissociate in the solution:

KOH(aq) → K+(aq) + OH-(aq)


Given:            [KOH] = 0.741 M

Ratio:             1 mol of KOH produces 1 mol of OH-
