Abstract The main task is the preparation of a nasal wash solution which can be divided into several subtasks and used as a source of chemistry problems. The experiment will expose the students to general laboratory practices as well as the concepts of solute, solvent, and mass percentage, which help students form the rigorous experimental attitude and realistic spirit.
