Inorganic Chemistry #5: Further Reactions and Uses of Group 2 Compounds (Slides and Tasks)

LESSON OBJECTIVE: Understand the trends in chemical properties and some of the uses of Group 2 compounds.

In this lesson we investigate chemical reactions of the Group 2 elements and their compounds and look at some uses of Group 2 compounds. This is lesson five in our inorganic chemistry series for Unit 10: Group 2 (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).

Learning Outcomes:
(taken from the Cambridge International AS and A Level Chemistry (9701) 2019-2021 curriculum)
10.1 Similarities and trends in the properties of the Group 2 metals, magnesium to barium, and their compounds
a) describe the reactions of the elements with oxygen, water and dilute acids

b) describe the behaviour of the oxides, hydroxides and carbonates with water and dilute acids

c) describe the thermal decomposition of the nitrates and carbonates

e) state the variation in the solubilities of the hydroxides and sulfates

10.2 Some uses of Group 2 compounds
a) describe and explain the use of calcium hydroxide and calcium carbonate (powdered limestone) in agriculture
