B.pharmacy Unit 3 Pharmaceutical Analysis Notes

B.Pharm Unit 3 – Pharmaceutical Analysis covers Precipitation titrations, Complexometric titrations, Gravimetric analysis, and Diazotisation titrations, which are important quantitative analytical techniques used in pharmaceutical quality control and drug analysis.

Bachelor of Pharmacy
Semester		1st Semester		Subject		Pharmaceutical Analysis
Syllabus
Unit 3rd	Precipitation titrations: Mohr’s method, Volhard’s, Modified Volhard’s, Fajans method, estimation of sodium chloride. Complexometric titration: Classification, metal ion indicators, masking and demasking reagents, estimation of Magnesium sulphate, and calcium gluconate.  Gravimetry: Principle and steps involved in gravimetric analysis. Purity of the precipitate: co-precipitation and post precipitation, Estimation of barium sulphate.  Basic Principles,methods and application of diazotisation titration

Precipitation titrations are based on the formation of an insoluble precipitate during the reaction between analyte and titrant.

Methods of Precipitation Titration

• Mohr’s Method: Uses potassium chromate as indicator
• Volhard’s Method: Back titration using thiocyanate
• Modified Volhard’s Method: Used in presence of precipitate
• Fajans Method: Uses adsorption indicators

SYLLABUS

Complexometric titrations are based on the formation of stable, soluble complexes between metal ions and chelating agents.

Classification

• Direct titration
• Back titration
• Replacement titration
