why 0.1M OR 1M Perchloric acid standardisation done after 24 hours?

Answer Posted / b.gangatharan

For non aqueous titrations,the solution should be virtually
anhydrous.Acetic anhydride present in 0.1M HCLO4 solution will absorb all the water from HCLO4 and Glacial acetic acid within 24 hours and renders the solution virtually anhydrous.

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?
