The half-reaction includes either the reduction or the oxidation reaction of the redox reactions. In acidic solution permanganate ion will react with hydrogen ion to yield manganese ion and water.
<h3>What are Redox reactions?</h3>
Redox or oxidation-reduction reactions are the chemical reactions in which the oxidation and the reduction of the chemical species occur simultaneously.
Permanganate (VII) ion is a strong oxidizing agent and gets easily reduced to manganese ion in presence of the hydrogen ion in an acidic solution.
The balanced half-reaction for reduction is shown as,

The question is incomplete. Here is hte complete question.
The components of poison ivy and poison oak that produce the characteristic itchy rash are cathecols substituted with long-chain alkyl groups. The image is attached.
If you were exposed to poison ivy, which of the treatments below would you apply to the affected area? Justify your choice.
(a) Wash the area with cold water.
(b) Wash the area with dilute vinegar or lemon juice.
(c) Wash the area with sopa and water.
(d) Wash the area with soap, water and baking soda (sodium bicarbonate)
Answer: (d) Wash the area with soap, water and baking soda.
Explanation: Alkyl is hydrophobic, which means it doesn't "mix" with water. To make it more soluble in water, soap helps to dissolve the chemical compound. As shown in the image, alkylcathecol is mildly alkaline. Baking soda is a salt that also helps dissolve it by ionizing with the -OH group, which makes it more soluble.
Although lemon juice and vinegar are acids, they are weak acids and so, won't have a strong effect on the alkylcathecol.
As said before, alkyl is hydrophobic, so plain water won't affect in any way the cathecol.
