Transport Number of Ions 441 dissociated into the long-chain ion and the simple ion of opposite sign (contra-ion or gegenion). Over the second range the conductivity falls extremely rapidly to about one-half its initial value. This rapid fall was discovered by McBain for solutions of -the soaps and he attributed it to depression of ionization.

The transport number is equal to the ratio of the velocity, or mobility, of a given ion to the sum of the velocities, or mobilities, of the cation and anion. It is a characteristic dependent on the mobilities of all the ions in the electrolytic solution, on the concentrations of the ions, and on the temperature of the solution.

1) find the molar mass of MgCl2 = 95.211 2) calculate the no. of moles = mass/molar mass = 9.53/95.211= 0.100093476 3) multiply the no. of moles by the no. of ions, there are 3 ions So, 0.100093476 * 3 = 0.300280429 4) now, multiply this answer by the Avogadro's constant and you get 1.81 x 10^23

These atoms are attracted by other similar atoms by van der Waal’s force of attraction and thus form small metallic particles. This is how both ions and particles are produced by the electrolysis process. Typically 90% of the silver leaving the anode stays in the ionic form while about 10% forms into particles.
