Web7 aug. 2024 · Diagonal lines indicate an E∘ cell that is pH -dependent. Vertical lines indicate 100% pH dependence. Horizontal lines indicate 0 % pH dependence. As a cursory example, for a given E∘ cell, the Mn3O4/Mn(OH)2 half-reaction equilibrium in basic media is: Mn3O4(s) + 4H2O(l) +2e− ⇌ 3Mn(OH)2(s) + 2OH−(aq)
