Which of the following ions would exhibit the greatest condu

Which of the following ions would exhibit the greatest conductivity? Explain your answers.

a) Li⁺ or Cs⁺

b) Mg²⁺ or Al³⁺

Solution

A. The conductivity of Li+ is greater than Cs+. This is because, in general, smaller ions have greater conductivity as there is less resistance as they move through the solution.

B. Al3+ has greater conductivity as Al3+ is smaller in size.
