Q15. The following cell was observed to have an emf of 2.30 volts at 25.0oC :
Zn(s) | Zn2+(aq, 0.131 M) || Cl2(g, 0.617 atm) | Cl-(aq, ?M) | Pt(s)
Use tables of standard reduction potentials in Petrucci to calculate the concentration of chloride ion in the cathode compartment, [Cl-] / M.
Your answer should be dimensionless (no units) and be given to 2 significant figures.
Scientific notation should be entered as 6.2e-3 for 6.2 x 10-3.
