Writing Skeletal Equations

Postby 004643111 » Mon Feb 08, 2016 1:58 am

For Chap 14 #1a, the chemical equation is
O3+Br^- -> O2+BrO3^-
and for the skeletal equations, it is said to be O3 -> O2. Why isn't it O3 -> BrO3^- since both sides contain ozone?

If you use O3 to BrO3- as the first equation than the only things you have left to make the other half reaction are Br and O2 which do not have any possible reaction together unless other reactants and products are added. So to make the overall reaction from the two half reactions you must use the Br and the BrO3 together so as not to add extra reactants or products not in the net equation.

Because BrO3 is the term corresponding with Br.

Br ---> BrO3 can also be balanced with the addition of H20 and H+ ions while Br ---> O2 would not react in the same way
