Aktinos Pharma Junior Executive Quality Control Interview Questions and Answers

pH is a measure of the acidity or alkalinity of a solution.

• pH stands for 'potential of hydrogen'.

• It is a logarithmic scale ranging from 0 to 14.

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.

• pH is determined by the concentration of hydrogen ions in a solution.

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9.

PH represents the concentration of hydrogen ions in a sample.

• PH is measured on a scale of 0-14, with 7 being neutral.

• A lower PH indicates higher acidity, while a higher PH indicates higher alkalinity.

• PH can be measured using a PH meter or through chemical indicators.

• The PH of a sample can affect its chemical properties and reactions.

LOD stands for Limit of Detection. It is the lowest concentration of a substance that can be reliably detected.

• LOD is used to determine the sensitivity of an analytical method.

• It is usually expressed as a concentration or mass.

• Water is a chemical compound composed of hydrogen and oxygen, while LOD is a term used in analytical chemistry.

• LOD is important in environmental testing to determine the presence of contaminants ...read more

There are various types of distillation techniques used in chemistry, such as simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used to separate liquids with different boiling points.

• Fractional distillation is used to separate liquids with similar boiling points.

• Steam distillation is used to extract volatile compounds from plants or organic materials.

• Other types of distillation...read more

• I have experience operating a fractional distillation column.

• I am familiar with the principles and techniques of fractional distillation.

• I have successfully used a fractional distillation column to separate mixtures of liquids based on their boiling points.

• I can provide examples of specific mixtures I have separated using a fractional distillation column.
