Calculate the volume of 0.540 M sodium hydroxide solution contains 11.5 grams of sodium hydroxide?
Considering the given reaction Cr3+(aq)+ 3e- → Cr(s) Eo = -0.74 V, Hg2+(aq)+ 2e- → Hg(l) Eo = +0.789 V then calculate What is the standard cell potential of a Cr-Hg cell? Remember to switch ½ reactions to oxidation and to balance the number of electrons.
