IF THE COMPOUND PKA IS 5.3 WHY WE ARE ADJUSTING PH+/-2 OF
THE COMPOUNDS PKA. WHAT IS THE CONDITION
Answers were Sorted based on User's Feedback
pKa=pH+log [un ionised]/[ionised]
at the half neutralisation point
un ionised concentration= ionised concentration
so pKa=pH+log1
pKa=pH because log1=0
if we didnt adjudt pH +/-2.0 we may get peak split because
for un ionised we get one peak and ionised we get one more
peak

Hello Dear all; I have a technical question related to analytical Chemistry, I have a sample of (40% w/w) Ferric Chloride solution (for water treatment purposes which consist a little portions of Ferrous Chloride and Hydrochloric acid. I need to know the methods to determine the percentages of each Ferrous Chloride and Chloride acid. Also I want to make sure that this solution is truly (40% w/w). So ANY CLUE !!! Thanks in advance.
how to get accurate result for Residue on evaporation in purified water
I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
