Which of the following will not be oxidized by ozone ?
Which of the following will not be oxidized by ozone ?
Updated On: Aug 1, 2022
- $KI$
- $FeSO_4$
- $KMnO_4$
- $K_2MnO_4$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$KMnO_{4}$ cannot be further oxidized by $O_{3}$. It has the highest $+7$ oxidation state of Mn in it. Alkaline $KI$ is oxidised to potassium iodate and periodate.
$KI+3O_{3} \to \underset{\text{Pot. iodate}}{{KIO_{3}}}+3O_{2}$
$KI+4O_{3} \to \underset{\text{Pot. periodate}}{{KIO_{4}}}+4O_{2}$
It oxidises manganate to permanganate
$2K_{2}MnO_{4} + H_{2}O+O_{3} \to 2KMnO_{4}+2KOH+O_{2}$
Acidified ferrous sulphate is oxidized to ferric sulphate
$2FeSO_{4}+H_{2}SO_{4}+O_{3} \to Fe_{2} (SO_{4})_{3} + H_{2}O+O_{2}$

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
