Concept

Problem: 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)A) 2B) 3C) 6D) 8E) none of the above

FREE Expert Solution

We are being asked to balance the given oxidation-reduction reaction and identify the coefficient of iodide ion.


The reaction is under acidic conditionsWhen 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+)
