Aalidhra Pharmachem Interview Questions, Process, and Tips

To make 0.1N NaOH from 1N NaOH standard solution, dilute 10 mL of 1N NaOH with distilled water to a final volume of 100 mL.

• Measure 10 mL of 1N NaOH solution

• Transfer the measured solution to a 100 mL volumetric flask

• Add distilled water to the flask until the volume reaches 100 mL

• Mix the solution thoroughly to ensure uniformity

HPLC and GC are both analytical techniques used in chemistry, but they differ in the type of samples they can analyze.

• HPLC stands for High Performance Liquid Chromatography, while GC stands for Gas Chromatography.

• HPLC is used for analyzing samples that are soluble in liquid, while GC is used for analyzing samples that can be vaporized.

• HPLC uses a liquid mobile phase and a solid stationary phase, while GC uses a gas mob...read more

QC focuses on testing the final product, while ADL focuses on testing the process and raw materials.

• QC is done on finished products, while ADL is done on raw materials and process

• QC is reactive, while ADL is proactive

• QC is concerned with product quality, while ADL is concerned with process quality

• QC is done by quality control department, while ADL is done by analytical development department

Habber process is used to prepare ammonia by reacting nitrogen and hydrogen under high pressure and temperature.

• The process was developed by Fritz Haber and Carl Bosch in early 20th century.

• The reaction takes place in presence of iron catalyst.

• The optimum conditions for the reaction are 200-300 atm pressure and 400-550°C temperature.

• The reaction is exothermic and releases heat.

• The produced ammonia is used as a fertiliz
