   15 Απρ 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.

   21 Ιουλ 2020 · pH Calculation Formula. The formula to calculate pH is: pH = -log[H +] The brackets [] refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may be given concentration in other units. To calculate pH, first convert concentration to molarity.

   What is the pH of a 5.0 mM solution of ammonia? Ammonia is a weak base Kb = Kw/Ka(NH4+) = 1.01⋅10-14/5.70⋅10-10 = 1.77*10-5 CH3OO-+ H 2O ↔ CH3OOH + OH-Kb = 1.77⋅10-5 = [NH 4 +] [OH-] / [NH 3] Let x = [NH4 +] Kb = x(x + [OH-] H2O) / (0.005 – x) Make assumptions: (1) [OH-] H2O <<< [OH-] NH3 (2) [NH3] = FNH3 The Kb expression reduces to
