There is a mistake in problem 20.24(d) in the 12th ed. and 20.26(d)
in<br>
the 13th and 14th ed. in the textbook. Based on what I know (and I<br>
discussed with others) we've concluded the mistake most likely lies<br>
with the problem itself. <br>
<br>
It lists one of the products as being Br^-(aq). That is unlikely
based <br>
on what the usual 1/2-rx is in acid for BrO3^- and the fact the Br^-
<br>
and BrO3 would actually react with each other to form Br2 (bromine).
<br>
So instead of Br-(aq) it should have Br2(<font face="Times New
Roman, Times, serif"><i>l</i></font>) (liquid bromine). It makes
<br>
much more sense this way based on the 1/2-rx given in Appendix D <br>
and the answer in the solutions manual. Turns out, it has been
corrected<br>
to Br2(<font face="Times New Roman, Times, serif"><i>l</i></font>)
in the MC on-line homework.<br>
<br>
Also, many of the answers in the solutions manual leave out most of
<br>
the intermediate steps and show only the final 1/2-rxs. Do the
problems <br>
the way I showed in lecture (and as shown in the book) and you
should <br>
get the 1/2-rxs shown in the solutions manual. <br>
