Buffer solution ice table
WebThere are some restrictions in the preparation of a buffer. Unlike a weak acid equilibrium, where an ICE table is needed to determine the degree of equilibrium concentrations of the weak base, the weak base is added directly to the solution, so the concentrations of HA and A- in the initial line in the ICE table is already accounted for. WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base.

WebNov 6, 2014 · When you used the ICE method the second time, you forgot that HA does not have an initial concentration of 0. Instead, the initial concentration of HA is 0.0091 as you calculated previously.
