0.1 M H2SO4solution is diluted to 0.01 M H2SO4?.Hence its molar conduc...
To understand why the molar conductivity of a 0.1 M H2SO4 solution is 10 times greater than that of a 0.01 M H2SO4 solution, we need to consider the concept of molar conductivity and the effect of dilution on conductivity.
Molar Conductivity:
Molar conductivity is a measure of the ability of a solution to conduct electricity. It is defined as the conductivity of a solution containing 1 mole of electrolyte in a given volume. Molar conductivity is represented by the symbol Λ.
Effect of Dilution on Conductivity:
Dilution of a solution involves adding more solvent to decrease the concentration of the solute. In the case of an electrolyte solution, dilution decreases the concentration of ions present in the solution, which in turn affects its conductivity.
When a solution is diluted, the number of ions per unit volume decreases, leading to a decrease in conductivity. However, the decrease in concentration is not proportional to the decrease in conductivity. In fact, the molar conductivity increases as the solution is diluted.
Explanation:
In this case, we are comparing the molar conductivity of a 0.1 M H2SO4 solution with that of a 0.01 M H2SO4 solution.
1. Initial Molar Conductivity:
The initial molar conductivity of the 0.1 M H2SO4 solution will be higher than that of the 0.01 M H2SO4 solution due to the higher concentration of ions in the former.
2. Dilution:
When the 0.1 M H2SO4 solution is diluted to a concentration of 0.01 M, the concentration of H2SO4 ions decreases. However, the decrease in concentration is not proportional to the decrease in conductivity. The molar conductivity of the diluted solution will be higher than expected.
3. Reasoning:
The molar conductivity of a solution increases as it is diluted because the decrease in concentration is offset by the increased mobility of ions due to the increased spacing between them. This increased mobility of ions leads to a higher molar conductivity.
4. Conclusion:
Based on the above reasoning, it can be concluded that the molar conductivity of a 0.1 M H2SO4 solution is 10 times greater than that of a 0.01 M H2SO4 solution. Therefore, the correct answer is option 'c' - 10 times.
