Acid-base titration combined with indicators is a method in analytical chemistry for the preliminary assessment of corresponding solutions. As a result, the first conclusions concerning the concentration of the analysed substance can be made

During this experiment, the students have to determine the unknown concentration of hydrochloric acid (solution to be analysed) with the aid of a suitable indicator (here: bromthymol blue). For this purpose, a known volume of the acid is titrated with a volume of a sodium hydroxide solution of a known concentration (standard solution) until the indicator changes colour. The used volume of the standard solution and its concentration are then used to calculate the concentration of the solution being analysed.
