Estimation of Calcium
Estimate the Calcium by Permanganametric Titration, where calcium is precipitated as calcium-oxalate using ammonium oxalate in acidic medium.
Estimation of Calcium - Permanganametric Titration
Formula:
Percentage of Calcium = ( Volume of KMno4 * Normality of KMno4 * 250 * 100 * 20 / Sample weight * 25 * 1000) Where, KMno4 -Potassium permanganate
