Updated 14 Oct 2024

Q1. What is oxidation reaction, distillation its types?

Ans.

Oxidation reaction involves the loss of electrons, while distillation is a process of separating components based on their boiling points.

  • Oxidation reaction is a chemical reaction in which a substance loses electrons.

  • Distillation is a process of separating components in a liquid mixture based on their boiling points.

  • Types of distillation include simple distillation, fractional distillation, and steam distillation.

Q5. Distillation types Why we choose this type

Ans.

Distillation types are chosen based on the properties of the substances being separated and the desired outcome.

  • Different distillation types include simple distillation, fractional distillation, and steam distillation.

  • Simple distillation is used for separating substances with significantly different boiling points.

  • Fractional distillation is used when the boiling points of the substances are closer together.

  • Steam distillation is used for separating temperature-sensitive compou...read more

Q6. Explain Hplc, Gc?

Ans.

HPLC and GC are analytical techniques used in chemistry to separate, identify, and quantify components in a mixture.

  • HPLC stands for High Performance Liquid Chromatography, used for separating compounds in a liquid mixture based on their interactions with a stationary phase and a mobile phase.

  • GC stands for Gas Chromatography, used for separating compounds in a gas mixture based on their partitioning between a stationary phase and a mobile phase.

  • Both techniques are widely used ...read more
