High school practicum “Acid-base titration.”
As part of the diploma curriculum they have to acquire a series of experimental skills. The preparation of solutions and titration (concentration titrations of an unknown solution from a known solution) are part of these skills.
In the image we can observe the final result of an acid-base titration, the indicator used (phenolphthalein) changes to a pink color in basic medium, indicating the end of the reaction.
