Alkaline solutions can be obtained from areaction of base metals with water. - The formation of the alkalme solution is indicated by the change in conductivity (the filament lamp lights up or starts to glow more intensively) and by the change in colour of the indicator.

Tasks

Prepare an alkaline solution of lithium and study the conductivity during the reaction.

Benefits
