Which statement is not correct:a)Conductance of an electrolytic soluti...
Conductance and Equivalent Conductivity of Electrolytic Solutions
Conductance and equivalent conductivity are two important properties of electrolytic solutions. Let's understand them in detail.
Conductance of Electrolytic Solutions
Conductance is the ability of an electrolytic solution to conduct electricity. It is expressed in units of Siemens per centimeter (S/cm). The conductance of an electrolytic solution depends on various factors such as:
- The concentration of the electrolyte
- The nature of the electrolyte
- The temperature of the solution
- The area of the electrodes in the solution
Dilution and Conductance
The conductance of an electrolytic solution increases with dilution. This is because, when an electrolytic solution is diluted, the concentration of ions decreases, and the distance between the ions increases. As a result, there are more free ions that can conduct electricity, which leads to an increase in the conductance of the solution.
Therefore, option 'A' is correct.
Equivalent Conductivity of Electrolytic Solutions
Equivalent conductivity is another important property of electrolytic solutions. It is defined as the conductance of a solution containing one gram equivalent of the electrolyte between two electrodes placed one centimeter apart. It is expressed in units of Siemens per centimeter per gram equivalent (S/cm/eq).
Dilution and Equivalent Conductivity
The equivalent conductivity of an electrolytic solution decreases with dilution. This is because, when an electrolytic solution is diluted, the concentration of ions decreases, and the distance between the ions increases. As a result, the number of ions that contribute to the conductivity of the solution decreases, which leads to a decrease in the equivalent conductivity of the solution.
Therefore, option 'C' is correct.
Conclusion
In summary, the statement that is not correct is option 'B'. The conductance of an electrolytic solution increases with dilution, while the equivalent conductivity of an electrolytic solution decreases with dilution.

(b) is correct because if we dilute the solution then the number of ions in unite volume are decrease so the conductance is also decrease
