Explanation:
When a strong electrolyte is dissolved in a solvent, it dissociates completely into ions. The equivalent conductance of a strong electrolyte is a measure of how well it conducts electricity in solution. It is directly related to the number of ions present and their mobility.
Increase in number of ions:
When a strong electrolyte is diluted, more solvent molecules are added, resulting in the dissociation of more electrolyte molecules into ions. This leads to an increase in the concentration of ions in the solution. As the number of ions increases, the equivalent conductance also increases.
Increase in ionic mobility:
Ionic mobility refers to the ability of ions to move in a solution under the influence of an electric field. It depends on factors like the charge and size of the ions, as well as the viscosity of the solvent. When a strong electrolyte is diluted, the solvent molecules are further apart, allowing the ions to move more freely. This increases the ionic mobility, which in turn increases the equivalent conductance.
Conclusion:
In conclusion, the increase in equivalent conductance of a strong electrolyte with dilution is mainly due to an increase in the number of ions and an increase in the ionic mobility of ions. Both factors contribute to the overall conductance of the solution.
