FAQs on Variation of Conductivity and Molar Conductivity Video Lecture - Chemistry for JEE Main & Advanced

1. What is the relationship between conductivity and molar conductivity?
Ans. Conductivity is the measure of a material's ability to conduct electricity, while molar conductivity is the conductivity of a solution divided by the concentration of the electrolyte. They are related as molar conductivity is directly proportional to the conductivity.
2. How does temperature affect conductivity and molar conductivity?
Ans. Generally, as temperature increases, conductivity and molar conductivity also increase due to the increased mobility of ions in the solution. However, this relationship may vary depending on the type of electrolyte.
3. Can you explain the factors affecting conductivity and molar conductivity?
Ans. Factors affecting conductivity and molar conductivity include concentration of the electrolyte, nature of the solvent, temperature, and presence of impurities or other ions in the solution.
4. How are conductivity and molar conductivity measured in the laboratory?
Ans. Conductivity is usually measured using a conductivity meter, while molar conductivity can be calculated by dividing the conductivity of the solution by the concentration of the electrolyte in moles per unit volume.
5. What are some real-life applications of conductivity and molar conductivity measurements?
Ans. Conductivity and molar conductivity measurements are used in various fields such as chemical analysis, environmental monitoring, water quality assessment, and in the development of new materials with specific electrical properties.
