Explanation: Barium hydroxide is a strong base for both stages of dissociation: Ba(OH)2(s) → Ba2+ +2OH− So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: [H+][OH−] = 1.0 ×10−14M [OH−] = 2.0 × 10−1M [H+] = 5.0 ×10−14M And then pH = −log10([H+] = 5.0 × 10−14) = 13.30. Answer link diamond\u0027s new dart-750WebFeb 26, 2024 · As RbOH dissociates into Rb 1+ and OH 1-, the OH 1- concentration is also 1.9 x 10 -3. [H 1+] [OH 1-] = 10 -14, so the [H 1+] = 10 -14 / 1.9 x 10 -3 = 5.3 x 10 -12 . Take the negative log of this to get pH = 11.3. The log of 1.9 x 10 -3 is -2.72, but pOH is the negative of this which is 2.72. pH + pOH = 14, so you can calculate pH from this also. ciss charity
