QuestionElectrochemistry / moving boundary method
The transport number of ions in a 1·0 M solution of AgNO₃ was determined using a 0·3 M solution of Cd(NO₃)₂ in the moving boundary method. When a current of 15 mA was passed for 30 min, the boundary swept through a volume of 0·1 cm³. The transport number of Ag⁺ is (Faraday's constant = 96500 C mol⁻¹)
- (a) 0·36
- (b) 0·64
- (c) 0·71
- (d) 0·83
