Answer / balakrishnan

Actually Citric acid is having three COOH group, due to
this we should get three end point. This can be acheived by
using potentiometry titration(Measure the pH variation with
respect to Volume added). The pKa values are 3.15, 4.77 and
5.19. Each pKa contributes one end point.

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
