Identify the incorrect statement among the following.
- A Electrolytic conductance increases with increase in temperature
- B Conductivity does not depend on the viscosity of the solution
- C Conductivity depends on the size of the ions
- D Conductivity depends on the solvation of the ions
Answer & Solution
Correct Answer
(B) Conductivity does not depend on the viscosity of the solution
Step-by-step Solution
Detailed explanation
(1) Correct: With increase in temperature, kinetic energy of ions increases and viscosity of solvent decreases \(\to\) ions move faster \(\to\) conductance increases. (3) Correct: Larger ions move more slowly \(\to\) lower mobility \(\to\) lower conductivity. (4) Correct:…
