Redox Titration (KMnO₄ vs Mohr's Salt)

Standardizing KMnO₄ against Ferrous Ammonium Sulfate in Acidic Medium.

1. Burette Controls

Titrant KMnO₄ (Purple)

Analyte Mohr's Salt + H₂SO₄

Burette Reading 0.00 mL

Instructions:
Open the valve. Purple KMnO₄ drops will instantly turn colorless as they react. As purple swirls begin to linger, switch to drop-by-drop. Stop at the first Permanent Pale Pink color!

2. Chemical Principles

Redox Reaction: Permanganate oxidizes Ferrous (Fe²⁺) ions to Ferric (Fe³⁺) ions in an acidic medium.

MnO₄⁻ + 5Fe²⁺ + 8H⁺ → Mn²⁺ + 5Fe³⁺ + 4H₂O

Self-Indicator:
KMnO₄ acts as its own indicator.
• Before Endpoint: MnO₄⁻ (Purple) is reduced to Mn²⁺ (Colorless).
• At Endpoint: All Fe²⁺ is consumed. One extra drop of MnO₄⁻ imparts a pale pink color to the whole solution.
