QuestionElectrochemistry / transport number
Two electrolytes AX and BX were chosen to determine transport number using moving boundary method. It is given that:
I: The cation B⁺ moves slower than the cation A⁺
II: The electrolyte BX is denser than AX
Which one of the following is correct?
- (a) The transport number of A⁺ can be determined if AX is used as principal electrolyte and BX as indicator electrolyte
- (b) The transport number of B⁺ can be determined if AX is used as indicator electrolyte and BX as principal electrolyte
- (c) The transport number of X⁻ can be determined if AX is used as indicator electrolyte and BX as principal electrolyte
- (d) The transport number of A⁺, B⁺ and X⁻ can be determined if AX is used as principal electrolyte and BX as indicator electrolyte
