What is the oxidation number for iodine in Mg(IO3)2 ?
The oxidation number of iodine is 5 in Mg(IO3)2 which can be calculated as
Mg(IO3)2
MgI2O6
As we know that
Mg has +2
O has -2
So,
(+2) + 2I + 6 (-2)=0
2 + 2I - 12 =0
10+ 2I =0
10 = 2I
I =5
Answer: The oxidation state of iodine atom in the given compound is +5.
Explanation:
Oxidation state is the number that is assigned to an element when it gains or looses electrons. If an element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.
For the given chemical compound: \(Mg(IO_3)_2\)
We take the oxidation state of iodine atom be 'x'
Oxidation state of magnesium atom = +2
Oxidation state of oxygen atom = -2
Evaluating the oxidation state of iodine atom:
\(+2+2x+6(-2)=0\\\\x=+5\)
Hence, the oxidation state of iodine atom in the given compound is +5.
