Oxidation States of Nitrogen in Various Compounds

In different compounds, nitrogen can have different oxidation states. Let's explore the oxidation states of nitrogen in ammonia, aluminum chloride, ammonium nitride, and ammonium sulfate.

Ammonia (NH3): The oxidation state of nitrogen in ammonia is -3. This is because hydrogen has an oxidation state of +1, and there are three hydrogen atoms bonded to nitrogen, resulting in a total oxidation state of -3 for nitrogen.

Aluminum Chloride (AlCl3): The oxidation state of nitrogen is not relevant in aluminum chloride as it does not contain nitrogen.

Ammonium Nitride (NH4)3N: The oxidation state of nitrogen in ammonium nitride is -3. This is because the oxidation state of hydrogen is +1, and there are three hydrogen atoms bonded to nitrogen, resulting in a total oxidation state of -3 for nitrogen.

Ammonium Sulfate ((NH4)2SO4): The oxidation state of nitrogen in ammonium sulfate is -3. This is because the oxidation state of hydrogen is +1, and there are four hydrogen atoms bonded to nitrogen, resulting in a total oxidation state of -4 for nitrogen. The oxidation state of sulfur in the sulfate ion is +6, and the overall charge of the sulfate ion is -2. Therefore, the oxidation state of nitrogen can be calculated as follows: - 2(N) + 4(+1) + (-2) = 0 - 2N + 4 - 2 = 0 - 2N + 2 = 0 - 2N = -2 - N = -1 So, the oxidation state of nitrogen in ammonium sulfate is -3.

In summary, the oxidation state of nitrogen in ammonia, ammonium nitride, and ammonium sulfate is -3.
