Textbook Example 14.4: Writing a Cell Reaction

Postby Antonio Melgoza 2K » Wed Feb 03, 2016 7:59 pm

It asks to write the cell reaction for: Pt(s) | H2(g) | HCl(aq) | Hg2Cl2(s) | Hg(l).
The answer is Hg2Cl2(s) + H2(g) ----> 2Hg(l) + 2Cl^-(aq) + 2H^+(aq)
Why did the Cl and H split up?

HCl is a strong acid and will readily dissociate in water. It produces H+ and Cl- so are the dominant species in your reaction rather than the compound HCl.
