I'm LOST with acids and bases. Help?

Question

I'm in 2nd semester general chemistry, and while I understood the majority of the topics we covered in 1st semester, acids and bases are killing me!

1. Am I missing something obvious, or is the topic just inherently hard?

2. Any recommendations for websites that I could try to learn from? I need to start from the very basics.

Example of a problem I can't do:

Calculate the pH of a buffer solution made by mixing 25.00 mL of 0.2 M sodium acetate and 25.00 mL of 0.1 M HCl.
