According to the official PCI notice dated 1 September 2026, eligible registered pharmacists can now access the Pharmacist Awards Portal and submit their applications using their BH-P Number registered with the Pharmacy…
Estimation of Barium Sulphate by Gravimetry: Barium sulphate (BaSO₄) can be quantitatively estimated by gravimetric analysis. The method is based on the precipitation of sulphate ions as highly insoluble barium sulphate by adding a soluble barium salt, usually barium chloride (BaCl₂). The precipitate is separated by filtration, washed to remove soluble impurities, dried or ignited…
Fajans Method: Fajans method is a type of argentometric precipitation titration used for the quantitative determination of halide ions, particularly chloride, bromide and iodide. It is a direct titration method in which standard silver nitrate solution is used as the titrant and an adsorption indicator is used to detect the endpoint. The method is named…
Volhard’s Method and Modified Volhard’s Method: Volhard’s method is an argentometric precipitation titration used for the determination of halide ions, especially chloride, bromide and iodide. Unlike Mohr’s method, which uses potassium chromate as an indicator, Volhard’s method uses ferric ions (Fe³⁺) as the indicator. The method is based on the precipitation of halide ions with…
Mohr’s Method: Mohr’s method is a precipitation titration method (argentometric titration) used mainly for the quantitative determination of chloride (Cl⁻) and bromide (Br⁻) ions in a solution. It uses silver nitrate (AgNO₃) as the standard titrant and potassium chromate (K₂CrO₄) as the indicator. The method is based on the formation of a sparingly soluble silver…
Principle and Steps Involved in Gravimetric Analysis: Gravimetric analysis is a classical quantitative analytical technique in which the amount or concentration of an analyte is determined by measuring the mass of a pure compound containing the analyte. It is one of the most accurate methods of quantitative analysis because the final measurement is based directly…
Estimation of Sodium Benzoate: Sodium benzoate (C₆H₅COONa) is the sodium salt of benzoic acid and is widely used as a preservative in pharmaceutical preparations, foods, and beverages. It can be estimated by acid-base titration. Since sodium benzoate is the salt of a weak acid and strong base, it reacts with a strong acid such as…
Estimation of Weakly Acidic and Basic Substances: Non-aqueous titration is an acid-base titration carried out in a solvent other than water. It is especially useful for the estimation of weakly acidic and weakly basic pharmaceutical substances that cannot be titrated accurately in aqueous media. In water, weak acids and bases may undergo incomplete ionization, resulting…
