Molar conductivity

 Molar Conductivity:


Molar conductivity is the conductivity of a solution containing one mole of an electrolyte when placed between two parallel electrodes having a unit length and large distance apart.


Formula:


Λm = κ / c


Where:

- Λm = Molar conductivity

- κ = Conductivity of the solution

- c = Concentration of the electrolyte (in moles per cubic meter)


Key Points:


1. Molar conductivity increases with dilution.

2. It's a measure of the ability of an electrolyte to conduct electricity.

3. Strong electrolytes have higher molar conductivity than weak electrolytes.


Applications:


1. Understanding electrolyte behavior in solutions.

2. Studying ionic interactions and conductivity.


Important:


Molar conductivity helps in understanding the conductivity behavior of electrolytes in solutions, which is crucial in various electrochemical applications.

Continuous Charge Distribution

 Continuous Charge Distribution  A continuous charge distribution refers to a system where charge is spread over a region, such as a line, surface, or volume. The electric field due to a continuous charge distribution can be calculated using integration. Types of Continuous Charge Distributions: 1. Linear Charge Distribution: Charge is distributed along a line. 2. Surface Charge Distribution: Charge is distributed over a surface. 3. Volume Charge Distribution: Charge is distributed throughout a volume. Formula: The electric field due to a continuous charge distribution is calculated using the formula: E = ∫ dE Where:  dE = Electric field due to a small element of charge  Applications:  1. Calculating electric fields: For complex charge distributions. 2. Understanding charge behavior: In various systems, such as capacitors and conductors. Some examples of continuous charge distributions: 1. Uniformly Charged Rod: Calculate the electric field at a point on the axi...
