Indian Political Action Committee Junior Research Fellow Interview Questions and Answers

Titration is a laboratory technique used to determine the concentration of a substance in a solution.

• Titration involves adding a solution of known concentration to a solution of unknown concentration until a reaction is complete.

• Types of titration include acid-base titration, redox titration, and complexometric titration.

• In acid-base titration, an acid or base is titrated with a solution of the opposite type to determi...read more

A pH meter is a scientific instrument used to measure the acidity or alkalinity of a solution.

• It measures the concentration of hydrogen ions in a solution.

• The pH meter consists of a pH probe and a meter that displays the pH value.

• The probe is inserted into the solution and measures the voltage difference between the solution and a reference electrode.

• The pH value is calculated based on the voltage difference.

• Examples o...read more

Concentration conversions refer to the process of converting between different units of concentration, such as molarity, molality, and percent composition.

• Converting between molarity and molality involves taking into account the density of the solution.

• To convert from molarity to percent composition, you need to consider the molar mass of the solute.

• Concentration conversions are important in chemistry for accurately me

Principles of HPLC, UV, titration, and ALCOA.

• HPLC principle involves separation of components in a mixture using high pressure liquid chromatography.

• UV principle involves the measurement of the absorbance of light by a sample at a specific wavelength.

• Titration principle involves the determination of the concentration of a solution by reacting it with a standard solution of known concentration.

• ALCOA principle stands for...read more

Accounting concepts and principles are the foundational guidelines for the preparation and presentation of financial statements.

• Accounting concepts are basic assumptions, rules, and guidelines that underlie the preparation of financial statements.

• Accounting principles are the rules and guidelines that companies must follow when reporting financial data.

• Examples of accounting concepts include going concern, consistency,...read more

HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interaction with a stationary phase and a mobile phase.

• HPLC stands for High-Performance Liquid Chromatography.

• It is widely used in various industries such as pharmaceuticals, food and beverage, environmental analysis, and forensic science.

• HPLC involves the use of a liquid mobile phase and a solid or liquid stationary pha...read more
