Hi!  I am working on a chem prac where we made an electrochemical cell - anode was Fe2+ cathode was Br2 in H2SO4

There is a question - why was the H2SO4 added to the Br2 solution???  I don't get it? Please *delete me*!

I am studying through distance ed so i can't ask the lecturer or students.  I have read the textbook on electrochem and got no clues.  In the same cell we used h2so4 for the salt bridge as well - is it related?? I know the salt bridge helps with ensuring neural charges in the 1/2 cells - is the H2S04 doing the same??

I think its because the substanced are easier to seperate in a Sulphuric Acid electrolyte, I'm not really shure but that seems to make sence to me

Cheers,

i think H2SO4 is added to let the reaction occur a bit faster.
