Achieve #10 (due week 3)

Hi,

Have we gone over how to do problems like this in class yet?

I don't remember having gone over the concept in class, but once you solve the question you can click on the solution and it explains the concept pretty well.

For this problem, you need to know a little about titration curves, which he didn't explicitly cover in lectures. It is, however, outlined in the sections of the textbook that we were supposed to read (I think section 6C). For these problems, you have to compare the pKa to the pH. For #10 on Achieve, since the pKa is less than the pH, the dominant species is the weak base (or neutral molecule).
