14.37 (c)

Postby Andy Liao 1B » Sun Feb 18, 2018 12:00 am

14.37 Determine the potential of each of the following cells:
(c) Pt(s) | Cl2(g, 250 Torr) | HCl(aq, 1.0M) || HCl(aq, .85M) | H2(g, 125 Torr) | Pt(s)

The cathode half-reaction for this cell reaction is 2H+(aq) + 2e- -> H2(g). I was wondering where the Cl from the HCl went. Can someone please explain why the Cl was omitted?

The Cl is the oxidation step such that Cl- becomes Cl and loses an electron as it forms a covalent bond with another Cl that has also lost an electron.
