Introduction Pharmaceutical analysis is a branch of analytical chemistry that focuses on the identification, determination, quantification, and quality control of substances used in the production of pharmaceuticals, as well as the analysis of pharmaceutical products themselves. Its primary aim is to ensure the safety, efficacy, and quality of drugs and pharmaceutical preparations. Here’s a note … Read more
Introduction Neutralization curves play a crucial role in acid-base titrations, helping to determine the equivalence point, pH changes, and appropriate indicators. These curves graphically represent the pH variation during titration, providing insight into the nature of the acid and base involved. Understanding neutralization curves is essential for analytical chemistry, pharmaceuticals, and various scientific applications. What … Read more
Introduction Acid-base indicators are substances that change color in response to changes in pH, making them essential in titration experiments to determine the equivalence point. Several theories explain how these indicators function, including Ostwald’s Ionization Theory, Quinonoid Theory, and the Modern pH Theory. Each of these theories provides insights into the mechanism by which indicators … Read more
Introduction An acid-base titration is a quantitative analytical method used to determine the concentration of an unknown acid or base by neutralizing it with a solution of known concentration. The process relies on the fundamental principles of acid-base reactions and involves different theoretical models to explain their behavior. The titration curve, which represents the pH … Read more
Introduction Acid-base titrations are quantitative analytical methods used to determine the concentration of an acidic or basic solution by reacting it with a solution of known concentration. These titrations are based on neutralization reactions and can be classified into different types based on the strength of the acid and base involved. 1. Classification Based on … Read more
Introduction An acid-base titration is a quantitative analytical technique used to determine the concentration of an unknown acid or base by reacting it with a standard solution of known concentration. The process is based on the neutralization reaction between an acid and a base, which produces salt and water. The endpoint is usually detected using … Read more

Introduction Alkalimetry, a type of volumetric analysis, determines the concentration of an alkaline (basic) substance by titrating it with a standard acid solution. Laboratories, pharmaceutical companies, food manufacturers, and water testing labs widely use this method to accurately quantify alkaline substances. Principle of Alkalimetry Alkalimetry is based on a neutralization reaction, where a base reacts … Read more
Introduction Acidimetry, a branch of volumetric analysis, determines the concentration of acidic substances in a solution by titrating with a standard base. Laboratories, industries, and pharmaceutical analysis commonly apply this method to quantify acidic content in various samples. Principle of Acidimetry The principle of acidimetry is based on a neutralization reaction, where an acid reacts … Read more
Introduction A solvent is a substance that dissolves a solute (a solid, liquid, or gas) to form a solution. It is usually present in a larger amount than the solute. Key Characteristics of a Solvent: Types of Solvents Used in Non-Aqueous Titration Solvents used in non-aqueous titration are classified into four major categories: 1. Aprotic … Read more
