The aim of this experiment is to show and explain to the students how indicators can be used in analytical chemistry. Furthermore, the students will find out the alkaline, acidic or neutral effects of different salts diluted in water.
During this experiment, the students have to determine the pH-value of the freshly prepared saline solutions with a suitable indicator (here: universal indicator).
What you can learn about
- pH value of different salt solutions
- Experiment literature available for pupils and teachers: Minimum preparation time
- Simple teaching and efficient learning by using the available interactive experiment literature
