Homework Help: Decomposition potential

  1. Nov 10, 2014 #1
    1. The problem statement, all variables and given/known data
    Decomposition potential can be affected by the concentration of sulphuric acid electrolyte and whether there is stirring. Explain how they affects.

    2. Relevant equations
    ED = Ecathode - Eanode + ɳ
    where ɳ is the overpotential

    3. The attempt at a solution
    I'm thinking that the decomposition potential here is referred to the experimental decomposition potential since overpotential is involved.
    Also, I think that the increase in concentration of the acid reduces the concentration polarisation same goes for stirring but I'm not sure whether I'm correct and I need help in linking back to decomposition potential

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    Decomposition of WHAT? Can you write a reaction for the decomposition? Where in that reaction might sulfuric acid (or some species derived from sulfuric acid) appear, or have an effect?
