Titrations!

The buret set-up

The titration lab consisted of finding the amount of NaOH that could be added to solutions of vinegar and KHP in order to determine the molarity of the NaOH and acetic acid. It was very cool to see the sudden color change from completely clear to pink when the equilibrium point was reached, but we had to be very careful when reaching that point because one drop over could result in inaccuracies in our calculations. This lab, although a little difficult to master at first, was one of the more enjoyable labs we have done all year.

Right before the color change

The color change; it turns a nice light pink!
