The conductivity of a solution is the ability of the solution to conduct electric current. It depends on the concentration of ions present in the solution. In the case of a solution containing sodium chloride NaCl , magnesium sulfate MgSO4 , and potassium nitrate KNO3 , increasing the concentration of these salts will increase the number of ions present in the solution.When the concentration of these salts increases, more ions Na+, Cl-, Mg2+, SO4 2-, K+, and NO3- are released into the solution. These ions are charged particles that can move freely in the solution, allowing the electric current to pass through it. As a result, the conductivity of the solution increases.In summary, increasing the concentration of sodium chloride, magnesium sulfate, and potassium nitrate in a solution will increase its conductivity due to the higher number of ions present in the solution.
