6L.7

Postby Joseph Saba » Sat Feb 22, 2020 12:41 pm

6L.7 Write the half-reactions and devise a galvanic cell (write a cell diagram) to study each of the following reactions:
(a) AgBr(s) --> Ag+(aq) + Br2(aq), a solubility equilibrium
(b) H+(aq) + OH-(aq)--> H2O(l)
How would i write the half reactions for these and the cell diagrams? Its confusing to me on how to split up the half reactions.

I’m also very confused because in the textbook answers, it says the anode reaction would be Ag + Br- —> AgBr + e- and the cathode rxn would be Ag+ + e- —> Ag. How are we supposed to infer this from just being given the reaction
AgBr <—> Ag+ + Br-
