what are the primary standards of redox titrations?Name any
two.

Answer Posted / sivabalan sinraj

1. Potassium Dichromate:K2Cr2O7, mol wt=294.19 g/mol

2. Oxalic acid can also be used in redox titrations because it will undergo the following reaction.
H2C2O4(aq) → 2 CO2(g) + 2 H+(aq) + 2 e-

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
