The last few times I've tested for TA, I put in the buffer drops and the drops that turn the sample green. I get to 6 drops of the reagent and after swirling the red disappears and we still have a green solution in the vial. On the 7th drop and the swirl, the green disappears ... But no red...we essentially have a clear solution in the vial. On the 8th drop of the reagent and swirl we then turn the full red.
So is my TA 70 or 80?
