Question:
Which of the following statement is true about potassium permanganate?
Which of the following statement is true about potassium permanganate?
Show Hint
Permanganate ion is tetrahedral, not square planar.
Updated On: Apr 21, 2026
- It is isostructural with \( KClO_3 \)
- It is paramagnetic in nature
- It oxidizes oxalates to carbon monoxide
- The structure of permanganate ion is square planar
- It is prepared by fusion of \( MnO_2 \) with an alkali metal hydroxide and an oxidising agent
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Concept:
KMnO\(_4\) is prepared by oxidation of MnO\(_2\).
Step 1: Preparation.
\[ MnO_2 + KOH + O_2 \rightarrow KMnO_4 \]
Step 1: Preparation.
\[ MnO_2 + KOH + O_2 \rightarrow KMnO_4 \]
