Question

Oxidation State of Nitrogen In [Co(NH3)5Cl]Cl2

Answer 1

Acc to oxidation no. Method it's oxidation state is +3

Answer 2

The oxidation state of nitrogen in $[Co(NH_3)_5Cl]Cl_2$ is -3.

Explanation:

• In the given compound, the element nitrogen is present ammonia.
• To find the oxidation of nitrogen in the given compound, the element attached to it must be identified.
• In case of $NH_3$, nitrogen is a non-metal. When hydrogen is attached to a non-metal it has +1 charge.
• In case of the given compound the sum of oxidation number of individual element present in the compound equals to zero as per the following equation:

$NH_3 = 0$

Let the oxidation state of nitrogen be 'X'

X + (+3) = 0

X + 3 = 0

X = -3

• Thus the oxidation state of nitrogen in $[Co(NH_3)_5Cl]Cl_2$ is identified as -3.
