Digitabytes 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 occurs.

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

• Titration is commonly used in the pharmaceutical industry to determine the purity of a drug or the concentration of an active ingredient.

• Examples of titration include acid-base titration, r...read more

UV stands for Ultraviolet.

• Ultraviolet radiation is a type of electromagnetic radiation with a wavelength shorter than that of visible light.

• UV radiation is commonly used for sterilization and disinfection purposes.

• Exposure to UV radiation can cause skin damage and increase the risk of skin cancer.

• UV radiation is also used in phototherapy to treat certain skin conditions such as psoriasis and eczema.

To prepare 0.1N HCL solution, dilute 8.3 mL of concentrated HCL to 1 liter with distilled water.

• Measure 8.3 mL of concentrated HCL.

• Add the measured HCL to a 1 liter volumetric flask.

• Fill the flask with distilled water up to the 1 liter mark.

• Mix the solution thoroughly to ensure uniformity.

There are several types of titrations used in analytical chemistry.

• Acid-base titrations

• Redox titrations

• Complexometric titrations

• Precipitation titrations

• Non-aqueous titrations

• Back titrations

• Direct titrations

• Indirect titrations

Neutralization is a chemical reaction in which an acid and a base react to form a salt and water.

• Neutralization is a type of chemical reaction.

• It occurs when an acid and a base react with each other.

• The products of neutralization are a salt and water.

• The reaction involves the transfer of protons from the acid to the base.

• The pH of the resulting solution is close to 7, indicating neutrality.

• Examples of neutralization reactions include the reaction between hydrochloric acid and...read more
