Scoring Scheme: 3-3-2-1 When you use the half reaction method to balance the redox reaction between one mole of NBS and ascorbic
acid to give L-dehydroascorbic acid and succinimide, how many moles of electrons are transferred?
1 answer:
<span>In the redox reaction between one mole of NBS and ascorbic acid, ascorbic acid undergoes oxidation reaction to form </span><span>L-dehydroascorbic acid.
On other hand, N-bromo</span>succinimide (NBS) undergoes reduction to form <span>succinimide.
Electron transferred during this process is two. Complete reaction is attached below for quick reference.
Thus, one molecule of NBS reacts with one molecule of </span>ascorbic acid, during this redox reaction. For each molecule reacting, two electrons are transferred.
Thus, when one mole of NBS reacts with one mole of ascorbic acid, 2 x Na moles of electrons will be transferred. It may be noted here that, Na = Avagadro's number = 6.022 X 10^23.
On other hand, N-bromo</span>succinimide (NBS) undergoes reduction to form <span>succinimide.
Electron transferred during this process is two. Complete reaction is attached below for quick reference.
Thus, one molecule of NBS reacts with one molecule of </span>ascorbic acid, during this redox reaction. For each molecule reacting, two electrons are transferred.
Thus, when one mole of NBS reacts with one mole of ascorbic acid, 2 x Na moles of electrons will be transferred. It may be noted here that, Na = Avagadro's number = 6.022 X 10^23.
