Quality Laboratory Incharge Interview Questions and Answers

Potassium Dichromate is a primary standard due to its high purity, stability, and ability to be accurately weighed.

• Potassium Dichromate has a high molar mass and is stable in air, making it a reliable substance for standardization.

• It can be accurately weighed and dissolved in water to form a solution of known concentration.

• It is also highly soluble in water, allowing for precise dilution.

• Potassium Dichromate is used as a primary standard in the calibration of analytical instr...read more

Potassium permanganate is not a primary standard due to its instability and tendency to react with impurities.

• Potassium permanganate is highly reactive and can easily react with impurities in the air or solution, leading to inaccurate results.

• It is also unstable and can decompose over time, making it difficult to maintain a consistent concentration.

• Primary standards are highly pure and stable substances that can be accurately weighed and dissolved to prepare a standard soluti...read more
