QA Executive Interview Questions and Answers for Freshers

Physical properties in analytical chemistry refer to characteristics of substances that can be observed or measured without changing their composition.

• Physical properties include color, odor, density, melting point, boiling point, solubility, and conductivity.

• These properties help in identifying and characterizing substances in analytical chemistry.

• For example, the melting point of a compound can be used to confirm its identity by comparing it to known values.

• Another example ...read more

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

• Titration involves slowly adding a solution of known concentration to a solution of unknown concentration until the reaction reaches its endpoint.

• The endpoint is usually indicated by a color change or other observable change.

• Titration is commonly used in analytical chemistry to determine the concentration of acids, bases, and other substances in a solution.

• Examples of titrat...read more

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 the energy changes that occur during these reactions.

• Chemistry is essential in fields such as pharmaceuticals, materials science, and environmental science.

• Examples include studying the properties of elements on the periodic table and analyzing chemical reactions ...read more

7 QC tools are a set of basic quality tools used for process improvement and problem-solving.

• The tools include: Pareto chart, cause-and-effect diagram, check sheet, control chart, histogram, scatter diagram, and flowchart.

• They are used to identify, analyze, and solve quality problems in a systematic way.

• For example, a Pareto chart can be used to identify the most common causes of defects, while a control chart can be used to monitor a process over time and detect any changes ...read more

Gas chromatography is a technique used to separate and analyze compounds in a gas mixture based on their interaction with a stationary phase.

• Gas chromatography involves a sample being vaporized and injected into a column with a stationary phase.

• Compounds in the sample interact differently with the stationary phase, causing them to separate based on their properties.

• The separated compounds are detected as they exit the column, allowing for identification and quantification.

• Gas...read more
