B. pharmacy 1st semester 

Pharmaceutical analysis - 1

This document is a B. Pharmacy 1st Semester exam paper focusing on Pharmaceutical Analysis-I, covering fundamental and advanced analytical techniques. Key highlights include:

• Core Concepts:

  • Primary Standards: Criteria and examples (e.g., K₂Cr₂O₇, As₂O₃).

  • Errors & Measurements: Systematic vs. random errors, significant figures (e.g., 0.0036 °C).

  • Solution Chemistry: Molarity, molality, percent weight/volume.

• Analytical Techniques:

  • Titrations: Acid-base (pH/pKa), redox (KMnO₄), complexometric (EDTA), and precipitation methods (Mohr’s, Volhard’s).

  • Electrochemical Methods: Potentiometry (calomel electrode), polarography (Ilkovic equation).

  • Gravimetric Analysis: Principles and precipitate handling precautions.

• Practical Applications:

  • Assay of compounds (e.g., sodium metabisulphite via iodometry).

  • Preparation and standardization of solutions (e.g., 0.1M KMnO₄).
