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 (...
The value of Ka for acetylsalicylic acid (aspirin) is 3.00×10−4. What is the value of Kb for its conjugate base, C9H7O4−? Dissociation Constant: The acid dissociation comes into the picture when a solution contains a weak acid, and it...
The control of acetylsalicylic acid group amount is preferably carried out by saponifying the polymer with NaOH, etc., in a mixed solvent of benzene and methanol.;COPYRIGHT: (C)1994,JPO&JapioSHIOMI TOMOOONDA YOSHIROOURA MAKOTOIMAI KIYOKAZU...
