JEE Mains · Chemistry · STD 12 - 2. Electrochemistry
A conductivity cell with two electrodes (dark side) are half filled with infinitely dilute aqueous solution of a weak electrolyte. If volume is doubled by adding more water at constant temperature, the molar conductivity of the cell will what?
- A increase sharply
- B remain same or can not be measured accurately
- C decrease sharply
- D depend upon type of electrolyte
Answer & Solution
Correct Answer
(B) remain same or can not be measured accurately
Step-by-step Solution
Detailed explanation
Solution is already infinitely dilute, hence no change in molar conductivity upon addition of water
