• Resumen

  • The titration of a strong acid with a strong base and the electrolysis of water are two classic laboratory exercises that are either performed or demonstrated in secondary school classrooms in order to introduce two important areas of chemsitry: acid-base chemistry and electrochemistry. In this experiment we have combined these two classical experiments into one complete laboratory experience. Here we report how the elctrolysis of an aqueous solution can be used to determine the concentration of hydrochloric acid in a coulometric titration.
