In the standard hydrogen electrode, platinum acts as the anode.
In oxidation 2 – propanol, acetone is produced which is a ketone.
In the «hydrogen–oxygen» fuel cell, the volume of gas consumed at the anode and cathode at STP conditions is equal.
From the reaction of one mole of formaldehyde with two moles of Cu(II) sulfate, one mole of oxalic acid and two moles of copper metal are obtained.
