Fine Tuning Testing Precedure w/ Taylor 2006

Carl - as always, very helpful.

With respect to #4, do you hold the container on a piece of white paper and look through? Or do you put a drop of water on white paper? Shouldn't have even a tinge of pink then?

BTW, I do love my new test kit...

another way to determine the correct endpoint of titrations (CH, TA, FC and CC) is to add the drops until NO MORE COLOR CHANGE occurs, then don't count the last drop added that didn't produce further color change. This will give you the endpoint with no confusion. Soon you will learn the endpoint colors and that last drop wont be needed.

Evan put it well.

I just put the container on a white paper, like the log on the lid and look for a tinge of pink.
