(YouTube Link) - Information about Acid Base reactions and equilibriums. Starting at about 7 minutes it covers titration information we will not do until Chp. 15 so it is also posted in Chapter 15's download page for the titration information at the end.
(YouTube Link) - This is a vodcast I made for watching later in the chapter (after we have talked about strong and weak acids and bases in class as well as salts). It goes over all the different categories of pH problems in this chapter (strong acid, weak base, salt of weak acid/strong base, etc) and how to solve them. It does not solve any specific problems, rather it shows you how identifying what your substance is can show you how to solve the problem.
