10. Picric acid was completely reduced in the coulometric cell according to the reaction equation
C6H2(OH) (NO2)3 +18H+ + 18е- = C6H2 (OH) (NH2) 3 + 6H20
The amount of electricity consumed was determined by the amount of iodine released in the iodide coulometer, the titration of which required V ml of 0.0200 M Na2S203.
Determine the mass of picric acid in solution (mg) according to the following data:
Option 1
V, ml 16.50
