Question

What is meant by transport number of an ion?

Answer 1

Transport Number or TransferenceNumber. (1) Definition: “The fraction of the total current carried by an ion is known as transport number, transference number or Hittorf numbermay be denoted by sets symbols like t+ and t– or tc and ta or nc and na

Answer 2

The transport number is defined as the fraction of the total current carried by an ion.

• The ion transport number is also called the transference number.
• The transport number of an ion is defined as the fraction of the total electrical current carried by an ionic species in a given electrolyte.
• Differences in electric mobility can cause differences in transport numbers.
• It is denoted by the terms 't+' and 't-'.
