Expert Answer:

  • The measurement of molar conductances (Lm) of solutions of coordination compounds helps to estimate the number of the ions furnishes by the compound in solution.
  • By comparing the molar conductance of the compound with those of known electrolytes, it was able to predict the number of ions present in the solution.

          For example:

          It has been observed that the complex CoCl3.6NH3 behaved as 1:3 electrolyte, CoCl3.5NH3 as 1:2 electrolyte, CoCl3.4NH3 as 1:1 electrolyte.

          The coordination compound CoCl3.3NH3 behaved as molecular (non-electrolyte).
