Document Summary
The titration of a weak acid with a strong base brings into play almost every type a acid/base problem we have encountered so far. It involves weak acid, buffer, weak base, and strong base calculations. The key to successfully solving these types of titration questions is recognizing which situation you are in. In today=s lecture we will go through each stage of a wa/sb titration and solve for the ph. As you work through the question it will become apparent that wa/sb questions are much like buffers, i. e. , the solution involves two main steps: Consider 50 ml 0. 100 m hac and titrate this with 0. 100 m naoh. Comment simple w. a. buffer buffer; ph = pka buffer buffer. Initially we have 0. 100 m hac ka = 1. 8 10-5 . Before we add any strong base we have a simple weak acid solution. After we add 10. 0 ml 0. 100 m naoh . Initially we had 50. 0 ml 0. 100 m hac.
