"The \"Ion Transport Number\" is a quantity which indicates the different contribution of ions to the electric current in electrolytes due to different electrical mobility." . "\\(t_B = \\frac{i_B}{i}\\), where \\(i_B\\) is the electric current carried by the ion \\(B\\) and \\(i\\) is the total electric current."^^ . . . .
