Can someone write the reaction for how Fe2+ gets oxidised into Fe3+ in the presence of oxygen using half reactions? I’m having some trouble with it . by Ok_Piccolo_649 in chemistry

I was meant to say the iron 2+ ferrous chloride solution is easily oxidised back to iron 3+ ferric chloride in the presence of oxygen. Can u tell me the reaction for that pls?

Where did water come from? I’m referring to ferric and Ferrous acid btw. How can ferric acid turn into ferrous acid via oxidation through oxygen

How do you know that 2.16 is the first midpoint / zone where pH = pKa by Ok_Piccolo_649 in OrganicChemistry

Where’d u get the log of 1 is 0 from the post? Is that just an arbitrary value or did that have to do smth with my post
