Webb6. Do introduce some moisture - Sometimes when you are in an over-titration situation and the vessel is already very dark you can introduce a little moisture to bring the vessel back to equilibrium. This sometimes works and immediately the vessel turns from a dark burnt-red color to a light-yellow. 7. Do have a spare detector electrode on hand.
