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

So 1 mole of NaCl weighs 58.5g. So now we need to convert grams into moles by dividing mass in grams by the mass of 1 mole. So the number of moles of NaCl = 58.5/58.5 = 1 mole. So the concentration of NaCl is 1mol.dm−3. This means that in 1dm3 of solution there must be 1 mole of sodium ions. The number of particles in 1 mole is given by the ...

Ions are formed when the number of protons in an atom does not equal the number of electrons. If more protons are present, the ion is positive and is known as a cation; if more electrons are present, the ion is negative and referred to as an anion. Ions are highly reactive species.
