Question

A student measures the conductivity of a MgCl2 solution and determines it to be a strong electrolyte. The student incorrectly lists the species in solution as MgCl2. Give the correct list of species in the solution. A student measures the conductivity of an Fe2(SO4)3 solution and determines it to be a strong electrolyte. The student incorrectly lists the species in solution as O-2, S-2, Fe+3. Give the correct list of species in the solution.
