If enough of a monoprotic acid is dissolved in water to produce a 0.0124 M solution with a pH of 6.72, what is the equilibrium constant, p?a, for the acid? kindly consider the following when answering the question For weak acids that are so dilute or so weak that the pH of the solution lies between 6 and 7, the autoprotolysis of water must be taken into account when determining the p?a value. At equilibrium, there are four species in solution, the weak acid, HA, its conjugate, A−, H3O+, and OH−. Start by developing four equations that describe what is occurring in the solution at equilibrium.
