Statement (S): Speed of ions depends upon nature of ions only.
Explanation (E): Mobility of ions depends upon mass, charge and size of ions only.

View answer and explanation

Correct option: B

S is wrong but E is correct

Option B (S is wrong but E is correct) is correct because the speed of ions depends on factors other than just the nature of the ions, while the explanation correctly identifies the factors affecting ion mobility.
