Reaction of alkalis with aluminium - alkali strength

Article no: P7159300
Principle

On the basis of their reactivity, alkalis can be divided into strong and weak alkalis. Strong alkalis react with aluminium to form aluminates while at the same time hydrogen is released. The reactivity of the alkalis can thus be determined with the aid of the reaction time required for dissolving the aluminium.

Tasks

Study the reaction of several alkalis with aluminium.

 

Benefits
