Chemical Analysis of Glycerol-Sodium Periodate Method
Principle: In strong acidic medium, sodium periodate oxidizes glycerol with three hydroxyl groups into formic acid and formaldehyde. Formic acid neutralized with NaOH, Indicating endpoint with pH meter. Calculating Glycerol Content from Consumption of NaOH Standard Solution 2HCHO+HCOOH+2NalO3+H2O→CH2OH–CHOH–CH2 OH+2NalO4 …
