Question

1. Why does the conductivity of a solution decrease with dilution?
2.Suggest a way to determine the A°m value of water.​

Answer 1

• Conductivity of a solution is the conductance of ions present in a unit volume of the solution. On dilution the number of ions per unit volume decreases. Hence, the conductivity decreases.
• According to Kohlrausch's law.
• Λom(H2O) = Λom(HCl) + Λom(NaOH) – Λom(NaCl)
• Hence if we know the values of Λom for HCl, NaOH, and NaCl, then we can calculate the value of Λom for the water.
