Properties of lithium, sodium and potassium Principle In this experiment, the behavior of the alkali metals in the air as well as the flame coloring during their combustion are investigated.
The reaction products are dissolved in water, the pH being estimated using the phenolphtalein indicator.
Finally, the electrical conductivity of the alkali metals is investigated. Material Benefits - Experimental literature available for pupils and teachers: Minimum preparation time
- Hazard assessment for pupils and teachers available
- Easy teaching and efficient learning using the available interactive experiment literature
