Physical and chemical properties of the elements and compounds of Groups 1 and 2
The experiments and activities in this section focus on the physical and chemical properties of the elements and compounds of Groups 1 and 2. Flame colours, characteristic reactions and context-related experiments are included.
While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.
We are starting with GCSE-level experiments.

Experiments
-
Thermal decomposition of calcium carbonate
Some reactions involving the thermal decomposition of calcium carbonate, hydration of the calcium oxide formed and the reaction of limewater with carbon dioxide are investigated.
-
Solubility patterns among anions of the Group 7 elements
The experiments explore patterns of solubility among the anions of Group 7 elements with lithium, calcium and silver cations.
-
Flame colours – a demonstration
A spectacular demonstration experiment to show the vivid flame colours of a variety of metal salts.
