Conductivity of a solution is not affected by
- A addition of water
- B process of heating
- C addition of acetic acid
- D addition of ethanol
Answer & Solution
Correct Answer
(D) addition of ethanol
Step-by-step Solution
Detailed explanation
Conductivity of a solution is not affected by addition of ethanol as it is a covalent compound and it do not dissociate into ions to change the number of ions in the solution.
