diffusion-coefficient.docA solutionof pH1.2 was made from 2g sodium chloride (NaCl), 3.2g pepsin (800 – 2500iu mg-1)and 7ml 37wt% hydrochloric acid (HCl) was made up to 1000ml in DI water.

 

 

 

where Fi is Faraday ‘s constant, T is the temperature in Kelvin, R a gas constant, zi is the charge number on the species, D is the diffusion coefficient, Ci is the moistureconcentration and κ is the ionic conductivity.

 

Theconductivity of the solution was 2.4*10-4 Ω-1m-1.

 

I wouldlike to know how to calculate the Cl ion, Na ion, H ion diffusion coefficient?
