NEET Chemistry Functional Group Tests Assertion Reason Question
Assertion (A): The pink color of potassium permanganate is discharged during the test for oxalate ions. | Reason (R): Calcium oxalate precipitate reacts with dilute sulfuric acid to form oxalic acid, which reduces potassium permanganate.
Both A and R are true, and R explains A.
Both A and R are true, but R does not explain A.
A is true, but R is false.
