Principle

Precipitants are substances or a mixture of substances, which induce the precipitation of dissolved substances to insoluble solids, the precipitate. Precipitation experiments are often used everyday laboratory practice to identify minor ion concentrations. The aim of this experiment is to introduce the students to precipitation reactions, so students have to conduct precipitation reactions to determine various anions.

Learning objectives

•  Detection of anions
• General procedure of a precipitation reaction

Benefits

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