What would be the reduction potential of an electrode at298 K , which originally contained1K_(2)Cr_(2)O_(7) solution in acidic buffer solution ofpH = 1.0 and which was treated with 50% of the Sn necessary to reduce all Cr_(2)O_(7)^(2-)" to "Cr^(3+).Assume pH of solution remains constant. Given : E^(0)._(Cr_(2)O_(7)^(2-)//Cr^(3+), H^(+))= 1. 33 V , log 2 = 0.3 , (2.303RT)/F = 0.06 |
