WebJul 24, 2016 · 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 WebThe pH is then calculated using the expression: pH = - log [H 3 O +]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. The hydronium ion concentration is 0.0025 M. Thus: pH = - log (0.0025) = - ( - 2.60) = 2.60 Top Calculating the Hydronium Ion Concentration from pH
