Oxidation number of carbon in H2CO3 is,
Answers
Answer:
the oxidation number of carbon in H2CO3 is + 4
Let us find Oxidation number of carbon in H2CO3 is,
Explanation:
Oxidation number: It is defined as left over charge that is present on atom when the atom is present along with other atoms ".
Rules to assign and calculate oxidation number
1. The oxidation number in elemental state of atom is taken as zero.
2. The oxidation number of mono-atomic atoms like Na+ etc is taken as 1.
3. The oxidation number of Hydrogen is +1 when present with non metals and -1 when present with metals.
4. The oxidation number:
- oxygen is -2
- In peroxides it is -1.
5. The metals oxidation number is always positive and non metal in negative .
6. In compounds that have two atoms with different electro negativities, the oxidation number of more electronegative is taken as –ve and for less electronegative it is taken as positive.
The oxidation of carbon in H₂CO₃ ca be calculated as :
1 x 2 + x +3 x -2 = 0
2+x -6=0
2+x-6=0
x=+4
