Unit I – Complexometric Titrations, Gravimetry Analysis Details
Pharmaceutical Analysis I – BPharma 1st Semester (AKTU & PCI Syllabus)
At FirstHope, we offer precise, exam-oriented notes aligned with the PCI-approved B Pharma syllabus. Unit I of Pharmaceutical Analysis introduces key concepts like concentration methods, standard solutions, and analytical errors. Therefore, a strong grasp of this unit is vital for semester success and exams like GPAT and NIPER.
1. Precipitation Titrations
This section explains titrations based on the formation of a precipitate. It includes Mohr’s method, Volhard’s method, Modified Volhard’s, and Fajans method. These are mainly used for the estimation of sodium chloride (NaCl) by forming a silver chloride precipitate.
2. Complexometric Titrations
Here, titrations involve complex formation between metal ions and chelating agents like EDTA. The section covers classification, use of metal ion indicators, and masking/demasking reagents. It also explains the estimation of magnesium sulphate and calcium gluconate in pharmaceutical analysis.
3. Gravimetry and Diazotisation Titrations
Gravimetric analysis is based on weighing a precipitate to determine the amount of analyte. It includes steps involved, co-precipitation, and post-precipitation, with barium sulphate estimation as an example. The unit also introduces diazotisation titration, its principles, methods, and pharmaceutical applications.
