In this experiment a sodium chloride solution of unknown concentration but known volume is filled into a vessel and an indicator (here: fluorescein) is added. A silver nitrate solution with a known concentration (standard solution, 0.1 M) is filled into the burette and added dropwise to the solution being analysed until the indicator changes colour. The volume, which can be read off the burette, and the known concentration of the acid are then used to calculate the concentration of the base.
