• Any Group 1A metal when combined with OH-, H-, O2- or NH2- makes a strong base
• K (Group 1A metal) is paired with OH-
• KOH → strong 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-
Determine the [OH-] concentration of a 0.741 M KOH solution at 25°C.
