Complexometric titrations

Complexometric titrations Complexometric titration, also known as chelatometry, is a form of volumetric analysis. It’s particularly useful for determining a mixture of different metal ions in solution. The formation of a colored complex is used to indicate the end point of the titration. The reaction reaches equilibrium rapidly after each portion of titrant is added, … Read more

Precipitation Titrations

Precipitation titrations Precipitation titrations are a type of titration that involves the formation of a precipitate during the titration process. In a precipitation titration, a solution of a known concentration (the titrant) is added to a solution of the substance being studied (the analyte). The titrant reacts with the analyte to produce a precipitate, which … Read more

Acid Base Titrations

Acid base titrations Acid-base titration is a quantitative analytical chemistry technique used to determine the concentration of an unknown acid or base solution by neutralizing it with a standard solution of known concentration. The process involves the gradual addition of the titrant (the solution of known concentration) to the analyte (the solution of unknown concentration) … Read more

Errors in Pharmaceutical Analysis

Errors Errors in pharmaceutical analysis refer to the discrepancies between the standard values and the true value. These errors can affect the accuracy and reliability of pharmaceutical analysis, and it’s crucial to identify and minimize them to ensure the quality and safety of pharmaceutical products. In this article we will see sources of errors, types … Read more

Preparation and standardization of various molar and normal solutions

Preparation and standardization of various molar and normal solutions The process of determining the exact concentration (molarity) of a solution is known as standardization. Titration is a type of analytical procedure that is frequently used in standardization. A titration involves reacting an exact volume of one substance with a known amount of another substance. 1.Oxalic … Read more

Primary and Secondary standards

Introduction Primary and Secondary standards The standardization process involves comparing a solution to a standard solution to determine its precise concentration. We used standard substances in standard solutions and knew their concentrations precisely. Traditionally, standard solutions are classified as either primary or secondary standards. A primary standard is used to standardize a secondary standard solution. … Read more

Methods of Expressing Concentrations

Solution concentration In the techniques of quantitative analysis, the use of solution requires some basis for the expression of solution concentration. As a qualitative expression of concentration, we always use the words diluted or concentrated when referring to a solution. As the term dilute means, there is very little amount of solute is present and … Read more

Pharmaceutical Analysis- Scope and Different Techniques of Pharmaceutical Analysis

Introduction Pharmaceutical analysis is a branch of chemistry, which deals with the study of various processes that are involves- the identification, determination, quantitation and purification. It is mainly used for the separation of the components from the mixture and for the determination of the structure of the compounds that make up pharmaceuticals, and are combined … Read more
