Problem: The balanced half-reaction in which sulfate ion is reduced to sulfite ion is a __________ process.a. 2-electronb. 3-electronc. 4-electrond. 6-electrone. 1-electron

FREE Expert Solution

We’re being asked to determine how many electrons are involved in the half-reaction of conversion of sulfate (SO42-) to sulfite ion (SO32-)

In this case, we have to balance the redox reaction for this half-reaction.

SO42- → SO32-

Follow the steps below:

Step 1: Balance the non-hydrogen and non-oxygen elements first

Step 2: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

Step 3: Balance hydrogen by adding Hto the side that needs hydrogen (1 H: 1 H+)

Step 4: Balance the charges: add electrons to the more positive side (or less negative side)
