E Appendix 5—Coulometric Titration

The galvanostatic solntion for a conlometric cell has been given in Ref When switching on the cnrrent, the bonndary conditions are dddx = -t JIzYD at X = 0 and dddx = at x = L. The 

The galvanostatic solution for a coulometric cell has been given in Ref.2 7 When switching on the current, the boundary conditions are dddx= -teonilzPIT at x=0 and 5c 5x= t.mi/zFIf at x=L. The initial condition is Ac= c- c(t = 0) = 0 at t = 0. The result is (z. charge number of ion, internal reactions neglected)
