Best answer
The SI unit of equivalent conductivity is **siemens meter squared per mole (S·m²/mol)**.

To understand this in more detail, let’s break down the concept:

1. **Equivalent Conductivity**: This is a measure of a solution's ability to conduct electricity. It is defined as the conductivity of a solution divided by the molar concentration of the electrolyte. Essentially, it gives an idea of how well ions in the solution can conduct electricity on a per-mole basis.

2. **Conductivity**: The basic unit of electrical conductivity is the siemens per meter (S/m). Conductivity is a measure of a material’s ability to conduct an electric current.

3. **Equivalent Conductivity Formula**:
   \[
   \text{Equivalent Conductivity} = \frac{\text{Conductivity (κ)}}{\text{Concentration (C)}}
   \]
   Where:
   - **κ** is the conductivity of the solution.
   - **C** is the concentration of the electrolyte in moles per liter (mol/L).

4. **Unit Derivation**:
   - Conductivity has the unit siemens per meter (S/m).
   - Concentration has the unit moles per liter (mol/L) or moles per cubic meter (mol/m³).
   - When calculating equivalent conductivity, you divide conductivity (S/m) by concentration (mol/L), resulting in the unit S·m²/mol.

Thus, the SI unit for equivalent conductivity reflects how effectively a particular amount of electrolyte contributes to the overall conductivity of the solution.
