Writing Cell Diagrams

Postby Katelyn B 2E » Sat Mar 17, 2018 5:56 pm

I'm confused on how to write half reactions and construct cell diagrams for redox reactions that have only one product. Can someone explain how to write the half-reactions for a redox reaction like 2Ag(s) + Br2(g) --> 2AgBr(s)?

I think that we will be given a chart and then we combine some of them to form this single product reaction.

You need two half reactions in order to write a cell diagram. The example you provided is a whole cell and it can be broken up into two half-cells. With the half reactions from this, you write the anode on the left side of the salt bridge and the cathode on the right side.

a solid is always needed. know what the cathode and anode is
