Testing Alkalinity

[Kjayec]

When adding the drops of Alkalinity Titrant to my sample, when do I record the results?
When it starts to turn pink or continue adding until it is actually red in color?

You keep adding drops until the red stops changing in color. Then don’t count that last drop that didn’t do anything.
