What is the relationship between specific conductance and equivalent conductance?

Text Solution

AI Generated Solution

To understand the relationship between specific conductance and equivalent conductance, we need to define both terms and derive their relationship mathematically. ### Step-by-Step Solution: 1. **Define Specific Conductance (κ)**: - Specific conductance, also known as conductivity, is a measure of a solution’s ability to conduct electricity. It is defined as the conductance of a solution of unit length and unit cross-sectional area. The unit of specific conductance is S/m (Siemens per meter). 2. **Define Equivalent Conductance (Λ)**: ...
