As we dilute the solutions gradually conductivity of the solution also decreases. state the reason

Conductivity depends on the ions which are present in it, ie conductivity is directly proportional to the number of ions present in the unit volume of the solution

so conductivity will be according to the number of ion passed through the solution

example of pure water and salty water can be taken. pure water will not be having more conductivity but salty water will have more conductivity because salts or ions are dissolved in the solution thus conductivity increases

as we dilute the solution concentration goes down
