Dynamische titration
WebAug 17, 2024 · Titration is a way of measuring the concentration of something, usually the concentration of a substance in a solution. For example, you can use it to find the concentration of a solution of an acid. Titration is a type of chemical analysis. We consider it to be analysis because we use it to make a measurement. WebAdding the titrating solution to the titrand's solution. Using the red stopper at the bottom of the buret, slowly add the titrating solution to the titrand's solution one drop at a time. It is important to only let the titrating solution be added one drop at a time because the titration reaction can be very sensitive.
