O.S. of N = +3
Oxidation number of N is +4. Oxidation number of o+2.
thats 3+
N has +3 state on it.Each H have -1 state.
-3
HNO2, If ON for H: +1. ON for 02: -2 Then (+1) N 2(-2) (+1) N (-4) Therefore Nitrogen's ON is +3.
Oxidation number of N is +4. Oxidation number of o+2.
thats 3+
I think +3 oxidation state
N has +3 state on it.Each H have -1 state.
-3
The name gives the clue. If any chemical is described as '-ous' it has the lower oxidation state. If described as '-ic' , it has the higher oxidation state, Hence Ferrous chloride is 'Iron(II) chloride' ( FeCl2) Ferric chloride is 'Iron(III) chloride' ( FeCl3). Similarly with Nitric Acid and Nitrous Acid ( HNO3/HNO2) Sulphuric acid and Sulphurous Acid (H2SO4/H2SO3)
The oxidation state of Hg in Hg2Cl2 is +1.It has +1 state.
Zero.for an element in the free state oxidation no is always zero.
-3
HNO2, If ON for H: +1. ON for 02: -2 Then (+1) N 2(-2) (+1) N (-4) Therefore Nitrogen's ON is +3.
The oxidation state of N in HNO3 is +5. Oxygen is -2 and H is +!.
because the oxidation state of N decreases
