Question 32

Electrolysis

As the concentration of an electrolyte reduces, the conductivity

  1. A.reduces to zero
  2. B.decreases
  3. C.increases
  4. D.is unaffected
Show the answer and explanation

Answer: B (decreases)

Explanation

A more dilute solution has fewer ions in each unit volume to carry the current, so its conductivity decreases (it does not drop to zero).
