- What is the approximate amount (mL) of 95% ethyl alcohol that will be required to dissolve the sulfanilamide in boiling ethanol? Note that Solubility of sulfanilamide in ethanol (mg/mL) is as follows: 14 mg at 0 °C; 24 mg at 20 °C; 46 mg at 40 °C; 88 mg at 60 °C; 210 mg at 80 °C. Remember that the sulfanilamide used in the experiment contains 5% wt of impurity (fluorenone); therefore, (357mg) X (0.05) = 17.85 mg impurities; hence = 357 mg -17.85 mg = X mg pure Sulfanilamide. So, (X mg) (1mL/210 mg) = Y mL (80 oC) minimum warm ethanol needed.What would happen to the your Kc values if you used an absorptivity constant of 6000 M-1, when the actual value was 5000 M-1?
