For each of the following strong base solutions, determine OH-| and (H30+] and pH and РОН For 2.2 x 10-4 M KOH, determine [OH ] and (H30+). Express your answers in moles per liter to two significant figures separated by a comma. • View Available Hint(s) [OH-], [H3O*] = 2.2×10-44.5×10-11 M Previous Answers Correct Term 2: Correct answer is shown. Your answer 4.57-10-11 = 4.57x10-11 M was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. KOH is a strong base that completely dissociates into K+ and OH in an aqueous solution: KOH(aq) → K*(aq) + OH- (aq) Therefore, the concentration of OH is the same as the given concentration of KOH and is equal to 2.2 x 10-1 M. Then use the ion product constant, substitute the calculated value for OH, and solve for (H3O*]:
