Jubilant Ingrevia Production Chemist Interview Questions and Answers

Acidity is the measure of the concentration of hydrogen ions in a solution.

• Acidity is measured on the pH scale, which ranges from 0 to 14.

• A pH of 7 is neutral, while a pH below 7 is acidic and above 7 is basic.

• Acidity can affect the properties and behavior of substances, such as their solubility and reactivity.

• Examples of acidic substances include vinegar, lemon juice, and battery acid.

Indicators are used in quality control to determine the endpoint of a reaction or to indicate the presence of a specific substance.

• Indicators are used in titrations to determine the endpoint of a reaction.

• They can also be used to indicate the presence of a specific substance in a sample.

• Common indicators include litmus paper, phenolphthalein, and methyl orange.

• Indicators can be organic compounds or inorganic compounds.

Titration is a technique used to determine the concentration of a solution by reacting it with a solution of known concentration.

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

• The point at which the reaction is complete is called the endpoint.

• The endpoint is usually detected using an indicator, which changes color when the re...read more

Material testing involves analyzing the physical and chemical properties of materials to determine their suitability for specific applications.

• Material testing can include tests for strength, durability, corrosion resistance, and thermal properties.

• Common methods of material testing include tensile testing, hardness testing, and spectroscopy.

• Material testing is important in industries such as construction, aerospace, a...read more
