Predict the reaction that will occur when Cl2 and Br2 are added separately to a solution that contains both Cl- and Br-
Is the answer reduction for both?
2Br- --> Br2 & 2 electrons lost Eo = - 1.065 volts
Cl2 & 2 Br- --> 2 Cl- & Br2 Eo reaction = + 0.294 volts
+ve sign shows the preferred, product- favored reaction.
Hint: electrodeposition of copper.
