Technical data

Saline solutions and their effect on various indicators

Article no: P7510400

Principle

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).

Learning objectives

pH value of different salt solutions

Benefits

Experiment literature available for pupils and teachers: Minimum preparation time
Simple teaching and efficient learning by using the available interactive experiment literature
