A student has carried out a moving boundary experiment using K2SO4 as an electrolyte.
The data obtained was tabulated in the following Table.
Cation velocity 11.43 mms-1
Cross sectional area of tube 28.56 mm2
Transference number of cation 0.593
Anion concentration 0.025 mol dm-3
Calculate the current flow for the boundary moves as far as 45 mm.
