I have read that it depends only on pH of the solution at some place and at other place i have read that it depends on both the solution and the solvent. This created confusion..
The transfer coefficient of an electrochemical reaction is defined as the fraction of the applied voltage for a multiple electron transfer process affects the forward or backward reaction ( alpha)
If it a single electron transfer we name it as symmetry factor ( beta)
what ever may be the reaction it deals with only electrode potential
