Iit Jee and Chemistry Faculty Interview Questions and Answers

Electrophoresis is a technique used to separate and analyze molecules based on their size and charge.

• It involves applying an electric field to a gel or solution containing the molecules to be separated.

• The molecules move towards the opposite charge electrode at different rates depending on their size and charge.

• This allows for the separation and analysis of DNA, RNA, proteins, and other biomolecules.

• Examples include agarose gel electrophoresis for DNA analysis and SDS-PAGE fo...read more

Kohlrausch's law states that the molar conductivity of an electrolyte can be represented as the sum of the individual contributions of its ions.

• Kohlrausch's law is also known as the law of independent migration of ions.

• It is applicable to strong electrolytes only.

• The law states that the molar conductivity of an electrolyte is the sum of the molar conductivities of its cation and anion.

• The law is expressed as Λm = Λm⁰ + λ⁺ + λ⁻, where Λm is the molar conductivity of the electr...read more
