redox titration.

Never seen/remember this from general chemistry. How does one go about this?

Is this common on the exam? What sorts of question can it ask with this topic?

Redox titration is fair game. Is the above associated with a passage? You can approach these similar to how you approach acid / base titration. Do you feel okay about those?

Yes, I am fine with acid/base titrations.

No, this was a discrete practice w/o answers in an old MCAT book.

Do you have a question in mind that tests this concept? There just seems to be a possibility of having a lot of calculations

In an acid / base titration, the acid & base react until one completely neutralizes the other. Say I'm adding -OH to HCl. Once all the HCl is used up, the pH spikes up because the -OH is in excess. Knowing the concentration of -OH, and vol added, we can figure out some stuff about the acid.

Similarly, in a redox reaction one thing is oxidized and one thing is reduced. Once the neutralization point is exceeded, excess titrant builds up. Knowing the volume of titrant added to reach that point and concentration helps to figure out some stuff about the molecule in question.
