Balance the following skeleton reaction and identify the oxidizing and reducing agents: include the states of all reactants and products in your balanced equation. you do not need to include the states with the identities of the oxidizing and reducing agents. zn(s) + no3−(aq) → zn(oh)42−(aq) + nh3(g) [basic]

-) Oxidizing agent:

-) Reducing agent:

Explanation:

The first step is separate the reaction into the semireactions:

A.

B.

If we want to balance in basic medium we have to follow the rules:

1. We adjust the oxygen with

2. We adjust the H with

3. We adjust the charge with

Lets balance the first semireaction A. :

Now, lets balance semireaction B:

Finally, we have to add the two semireactions:

_________________________________________

Cancel out the species on both sides:

Simplifying the equation :

The is oxidized therefefore is the reducing agent. The is reduced therefore is the oxidizing agent.
