The reason why saturated solution of K N O 3 is used to make ‘salt-bridge’

Options

  1. AVelocity of K + is greater than that of N O 3 -
  2. BVelocity of N O 3 - is greater than that of K +
  3. CVelocities of both K + and N O 3 - are nearly the same
  4. DK N O 3 is highly soluble in water

Correct answer

C. Velocities of both K + and N O 3 - are nearly the same

Step-by-step solution

Velocities of both K + and N O 3 - are nearly the same in K N O 3 so it is used to make salt-bridge.
