WebWater in the glass of the buret can cause variations in the concentration of the base being used, reason why we rinse it with the base, so we have a good precision titration. The erlenmeyer can be rinsed only with distilled water, since the volume of acid solution used for the calculation is constant. You will have a equation that looks like this: Web6. 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.
