ExperimentThe reactivity of the group 2 metals
Compare group 1 and group 2 metals with this practical that shows their reactivity rates, where students can take control of their own observations and come to their own conclusions
-
ExperimentReacting elements with oxygen
Different members of the periodic table will exhibit different reactions when exposed to oxygen, often through heating. This practical supports students to understand the diversity of chemicals and their principles.
-
ExperimentProperties of the transition metals and their compounds
Student discover the diversity of transition metals in this practical that puts their knowledge of these common elements to the test. Includes kit list and safety instructions.
-
ExperimentThe oxidation states of vanadium
Introduce your students to the idea that different oxidation states of transition metal ions often have different colours, and that electrode potentials can be used to predict the course of the redox reactions. Includes kit list and safety instructions.
