pH is the minus logarithum of the concentration of H+ ion to
the base 10..scale 0 to 14 (discovered by SORENSON)
Less than 7-Acidic in nature
Greater than 7-Basic in nature
and equal to 7-neutral in nature
1st crireria is the soln must be an aqueous soln..
2nd thing its must be an electrolyte..
we can see pH value only that soln whose concentration is
below or equal to 1M...

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
