Balancing Half-Cell Reactions

Balance both equations by the half-cell method, showing both half-cell reactions and identifing them as oxidation or reducton.

a. Cl2(g)+ OH- <--> Cl- + ClO3- + H20(l)

b. SO4- + I- + H+ <--> S2- + I2(g) + H2O(l)

Balance both equations by the half-cell method, showing both half-cell reactions identifying them as oxidation or reduction.

a. Cl2(g)+ OH- <--> Cl- + ClO3- + H20(l)

Assuming that this reaction is in a basic medium, it is balanced as follows:

You must first balance non hydrogen and non oxygen atoms. Then balance oxygens by adding H2O and balance H by adding H+. Then we add the same number of OH- ions to each ...

Solution Summary

Solution shows calculations for finding both balanced redox reactions.
