TA test using K-2005 kit

[MikeInTN]

When testing for TA using my K-2005 kit, I'll reach a point where the sample will turn a faint reddish color, and hold that color (it won't flash back to green); the next subsequent drop of acid will cause the sample to turn a deep red color. Should I go with the reading (drop) that caused the initial color change, even though it's faint, or with the next drop which produces a deep, distinct red coloring? Or just go in between, as it's 10ppm per drop? Or should I quit being so anal about it, and just figure "what's 10ppm between friends?" :lol:

TIA,
Mike

If your still seeing color change keep adding drops until you see no change. Thats your end point. If you add 15 and it gets that bright red add one more. If it dosen't change your end point is 15 if it does....add another drop
