Answer 2

Mohr's salt can be used as the primary standard in permagnometry.

• Permagnomertry is a type of redox reaction.
• We know potassium permanganate is a strong oxidizing agent.
• Mohr's salt is a reducing agent.M
• In this reaction, Mn⁺⁷ of potassium permanganate reacts with the Fe²⁺ ion of Mohr's salt.
• Mn⁺⁷ (pink color) changes to Mn²⁺ (colorless)
