AP Extra Help File
Hi Octet,
Today, I posted a file that contains various Acid/Base problems. The examples are categorized and the full solutions are posted therein. Also, the answers to extra problems in the file are on the last page of the file.
Notice the problem on calculating the Ka of a weak acid given the pH at equilibrium of a certain concentration of the weak acid. We did not explicitly do a problem like this in class but, as long as you set up the ICE table properly (and understand what goes where within an ICE table), the problem is even easier than a typical weak acid pH calculation. Anyway, you've already done some Ka calculation problems already if you have been studying and doing the practice tests.
See you Monday.
