Estimation of Calcium - Permanganametric Titration

Estimate the Calcium by Permanganametric Titration, where calcium is precipitated as calcium-oxalate using ammonium oxalate in acidic medium.

Estimation of Calcium

  • Volume of KMno4

  • Normality of KMno4

  • sample weight

  •  

  • Percentage of calcium

Formula:

Percentage of Calcium = ( Volume of KMno4 * Normality of KMno4 * 250 * 100 * 20 / Sample weight * 25 * 1000)

 Where,
KMno4 -Potassium permanganate
