What are the products made in the electrolysis of an aqueous solution of calcium bromide?
ANS: Br(l) + H2(g) + OH-(aq)
Follow-up Q: why would calcium not be included in the reaction when it is the fourth from the bottom on the table of reduction half-reactions (see chem 30 data booklet).
NOTE: may need to Google Chem 30 data booklet for table of reduction half-reactions.
