Determination of acetylsalicylic acid by FIA-potentiometric system in drugs after on-line hydrolysis. Kubota L.T,Fernandes J.C.B,Rover L. et al. Talanta . 1999Kubota, L.T.; Fernandes, J.C.B.; Rover, L.; Neto, G.D. Determination of acetylsalicylic acid by FIA-potentiometric system in ...
the number of moles of NaOH that reacted with acetylsalicylic acid is 0.00435-0.001035 = 0.003495 therefore 0.003495 moles of NaOH reacted with the acetylsalicylic acid the mole ration between NaOH and acetylsalicylic acid is 1:2 meaning the number of moles of acetylsalicylic acid is 1/2 x 0.00...
First method was done using 1 M NaOH for degradation of acetylsalicylic acid and development of colors with 0.02 M FeCl3 in 0.03 HC1 (optimal pH = 1.6). For this analysis we made (multiple times) five standards with different concentrations (50-250%), changing pH of FeCl3/HCl solution (...
