We are being asked to balance the given oxidation-reduction reaction and identify the coefficient of iodide ion.
The reaction is under acidic conditions. When balancing redox reactions under acidic conditions, we will follow the following steps.
Step 1: Separate the whole reaction into two half-reactions
Step 2: Balance the non-hydrogen and non-oxygen elements first
Step 3: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)
Step 4: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
When the following redox equation is balanced with smallest whole number coefficients, the coefficient for the iodide ion will be _____.
I–(aq) + NO3–(aq) → NO(g) + I2(s) (acidic solution)
E) none of the above
