From [1] … WebAnswers: (a) pH = -log (4.0 x 10 -8 M ) = 7.4; (b) pH = -log (0.020 M ) = 1.7; (c) pOH = -log (0.040) = 1.4 so pH = 14-1.4 = 12.6; (d) pOH = -log (3 x 10 -3 M) = 2.5 so pH = 14-2.5 = 11.5; (e) pH = -log (6.0 x 10 -5? M ) = 4.2 (2) Find the hydronium ion concentration in a solution with pH = 4.83 Answer: [H+] = 10 -pH = 10 -4.83 =1.5 x 10 -5 M

WebJul 24, 2016 · pH = 13.30. 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. … WebDec 30, 2024 · You have added 49.00 × 10-3 L × 0.100 M NaOH = 4.90 × 10-3 moles of OH- ions. Then it remains 5.00 × 10-3 - (4.90 × 10-3) = 1.0 × 10-4 moles H+. The H + concentration is 1.0 × 10-4/ (0.049 L + 0.050 L) = 1.0 × 10-4/ (0.099 L) = 1.00 × 10-3 M. As pH = -log [H+], pH will be 3.
