Q7.* Oxidation state of nitrogen is incorrectly given for :

                 Compound                        Oxidation State

      (1) [Co(NH₃)₅Cl]Cl₂                             – 3

      (2) NH₂OH                                           – 2

      (3) (N₂H₅)₂SO₄                                   + 2

      (4) Mg₃N₂                                              – 3

Dear Student,

The Oxidation State Nitrogen (N) in the compound (N₂H₅)₂SO₄ is not correct.
The correct Oxidation State of Nitrogen (N) in the compound is -2.
This is explained below:

• Let the Oxidation state of N be 'x'.
• Oxidation State of Hydrogen is +1.
• Oxidation State of Sulphate is -2.
• Overall charge on the compound is 0.

So, the Oxidation State of N can be calculated as:

2 (2x + 5) + (-2) = 0

4x + 10 - 2 = 0

4x = - 8

x = - 2

Therefore, incorrect Oxidation State of Nitrogen (N) is given in option (3).

Hope this information clears your doubts about the topic.

Keep asking!!
