Question

There is a current being applied to an aqueous solution fo sodium bromide. What is produced at the cathode and anode?
I said that Na(s) being produced at the cathode and Br2(l) being produced at the anode.

The other options are H2 and O2 for either but those wouldn't make sense right?

Answer 1

Think about this for a minute. If Na is produced at the cathode wouldn't Na (a VERY active metal) react with H2O for form H2? Of course that doesn't happen that way, 2H+ + 2e ==> H2(g) is the product at the cathode. You may want to re-examine this question.

Answer 2

Oh i see that's where the reduction occurs now thanks dr bob!
