Please answer these questions on your Page 8 HA(aq) is a weak acid with a dissociation constant, K₁, of 7.7 x 10-¹2. What is the pH of a 0.011 M solution of A-(aq)? The temperature is 25°C. (b) For the reaction A(g) = A(1), the equilibrium constant is 0.666 at 25.0°C and 0.111 at 75.0°C. Making the approximation that the entropy and enthalpy changes of this reaction do not change with temperature, at what temperature will the equilibrium constant be equal to 0.777?

you prepare a solution of 3.1 x 10-8M KOH and calculate the pH in the typical way for a strong base: calculate pOH (7.51), then pH = 6.49. When you place a pH meter in the solution you find that the pH is actually 7.11. What was wrong with your calculation? (Brief conceptual explanation is fine here – no calculations needed.)
