I applied via Naukri.com and was interviewed in Aug 2023. There were 2 interview rounds.
Chemistry is the study of matter, its properties, composition, and interactions.
Chemistry involves understanding the structure and behavior of atoms and molecules.
It explores how substances react with each other and transform into new substances.
Chemistry is essential in fields like pharmaceuticals, food science, and environmental science.
Examples include studying the properties of elements on the periodic table and an
The pH formula is used to calculate the acidity or alkalinity of a solution.
pH = -log[H+]
pH = -log[H3O+]
pH = log(1/[H+])
pH = log(1/[H3O+])
There are 118 elements in the periodic table.
There are 118 known elements in the periodic table.
Elements are organized by atomic number, electron configuration, and recurring chemical properties.
Examples of elements include hydrogen, oxygen, gold, and uranium.
Noble gases are a group of chemical elements with very low reactivity and full outer electron shells.
Noble gases are located in Group 18 of the periodic table.
They are also known as inert gases because they rarely react with other elements.
Examples of noble gases include helium, neon, argon, krypton, xenon, and radon.
Avogadro's number is a constant representing the number of constituent particles (usually atoms or molecules) in one mole of a substance.
Avogadro's number is approximately 6.022 x 10^23.
It is named after Italian scientist Amedeo Avogadro.
It is used in chemistry to relate the mass of a substance to the number of atoms or molecules it contains.

I applied via Referral and was interviewed before Nov 2019. There were 3 interview rounds.
Normality refers to the state of being normal or conforming to a standard or average.
Normality is a concept used in various fields to define what is considered typical or expected.
It is often used in statistics to describe the distribution of data points around a mean.
In psychology, normality refers to behavior that is within the range of what is considered socially acceptable.
Normality can also be subjective, varying ...
Molarity is a measure of the concentration of a solution expressed as the number of moles of solute per liter of solution.
Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.
It is denoted by the symbol 'M'.
Molarity is commonly used in chemistry to express the concentration of a solution.
For example, a 1 M solution of sodium chloride contains 1 mole of sodium chloride
Molarity is the concentration of a solution in terms of the number of moles of solute per liter of solution, while molality is the concentration of a solution in terms of the number of moles of solute per kilogram of solvent.
Molarity is denoted by M, while molality is denoted by m.
Molarity is affected by temperature changes, while molality is not.
Molarity is used in chemical reactions, while molality is used in colliga...
HPLC stands for High Performance Liquid Chromatography. It is a principle used in analytical chemistry to separate, identify, and quantify components in a mixture.
HPLC uses a liquid mobile phase and a solid stationary phase to separate components based on their interactions with the stationary phase.
The principle is based on the differential partitioning of components between the mobile and stationary phases.
Components...
The principle of UV-spectrophotometer is based on the absorption of ultraviolet (UV) light by molecules.
UV-spectrophotometer measures the absorbance of UV light by a sample.
The absorbance is directly proportional to the concentration of the absorbing species in the sample.
The principle is used in various applications such as quantitative analysis, purity determination, and kinetics studies.
UV-spectrophotometer operates...
Quality assurance focuses on preventing defects while quality control focuses on identifying and correcting defects.
Quality assurance is a proactive process that involves planning, designing, and implementing processes to prevent defects from occurring.
Quality control is a reactive process that involves identifying defects and taking corrective action to eliminate them.
Quality assurance is focused on the entire process...

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle.
Data integrity ensures that data remains unchanged and reliable over time.
It involves maintaining the accuracy and consistency of data during storage, processing, and transmission.
Data integrity can be achieved through various measures such as checksums, encryption, and access controls.
Examples of data integrity issues ...
CAPA stands for Corrective and Preventive Action.
CAPA is a systematic approach to identify, investigate, and resolve quality issues.
It involves analyzing the root cause of the problem and implementing corrective actions to prevent recurrence.
CAPA is commonly used in industries such as manufacturing, pharmaceuticals, and healthcare.
Examples of CAPA tools and techniques include 5 Whys, Fishbone Diagrams, and Pareto Analy
Calibration is required to ensure accuracy and consistency of measurements and equipment.
Calibration helps to maintain the quality of products and services.
It ensures that measurements are accurate and consistent, reducing errors and improving efficiency.
Calibration is necessary for compliance with industry standards and regulations.
Examples of equipment that require calibration include scales, thermometers, and medica...
