Question details

Q8: Refer to the Pourbaix diagram for chromium in Figure below, the equilibrium reaction for the line separating the regions of passivation by Cr:Os and transpassive dissolution as chromate ions CrO corresponds to the reaction 2CrO (aq)+10H (aq)+e CrOs(s)+5H2O0) Show that the reduction potential for this half-cell reaction depends on both the pH and the concentration of dissolved chromate ions. The standard electrode potential for the reduction reaction is Eo 1.31 V vs. SHE. 2.0 1.5 1.0 crs 0.5 Cr O (passivity)CrO, Cr 12 16 pH
