Question

Sum of transport number of cation and anion of an electrolyte is equal to

Answer 1

Sum of transport number of cation and anion of an electrolyte is equal to 1 .

Answer 2

Sum of transport number of cation and anion of an electrolyte is equal to one

Explanation:

• Transport number or ion transport number is also called transference number
• It is the fraction of the total electrical current which is carried out in an electrolyte of a given ionic species.

• The concept of transport number was given by Johann Hittorf in  1853.

• Molar ion conductivities are calculated from the measured ion and transport numbers.
• Mainly Hittorf method is used for the determination of transport numbers.
