1. a. Draw the pH curve for a strong acid and a weak acid when a strong base is added. Note the in the case of the weak acid, the addition of the strong base yields a common ion (i.e conjugate base) when it is dissolved. b. Explain the difference between the two curves. (Hint: why is one curve showing a very small change in pH along y-axis in the acidic region when the strong base is added?
