Write the chemical formula for each of the following compounds,and indicate the oxidation state of nitrogen ineach: (a) nitric oxide, (b) hydrazine, (c) potassium cyanide,(d) sodium nitrite, (e) ammonium chloride, (f) lithiumnitride.
Write the chemical formula for each of the following compounds,
and indicate the oxidation state of nitrogen in
each: (a) nitric oxide, (b) hydrazine, (c) potassium cyanide,
(d) sodium nitrite, (e) ammonium chloride, (f) lithium
nitride.
Solution:
a) Nitric oxide , NO
oxidation state of N , x + (-2) = 0
x-2 =0
x=2
b) Hydrazine, N2H4
oxidation state of N , 2 x + 4(1)= 0
2x + 4 = 0
2x = -4
x = -2
c) Potassium cyanide , KCN
oxidation state of N, 1+2+ x =0
3+ x= 0
x = -3
d) Sodium nitrite , NaNO2
oxidation state of N, 1+ x + 2( -2) = 0
1-4+ x = 0
x = 3
