HILFIGED I PYLLO Write a balanced chemical equation for the reaction of NBS and Vitamin C. Cathg Of it Cytty Br NO2 Colhoof & Cuts NO₂ + H8r If the NBS solution was 0.100 M, how many moles were added at the equivalence point? How many moles of Ascorbic Acid would be neutralized then

Volume of NBS solution is 100ml

Answer 1

Sol.

Balanced chemical reaction of NBS , C4H4BrNO2 with Ascorbic acid , C6H8O6 :

C4H4BrNO2 + C6H8O6 -----> C6H6O6 + C4H5NO2 + HBr  

As Volume of NBS = 100 mL = 100 / 1000 L = 0.100 L

Molarity of NBS = 0.100 M

So , Moles of NBS added at the equivalence point

= Molarity of NBS × Volume of NBS

= 0.100 M × 0.100 L

=   0.010 mol  

From reaction ,

Moles of Ascorbic acid would be neutralized

= Moles of NBS added at the equivalence point

=   0.010 mol
