Module 3 | Reactive chemistry
Content 2: Predicting reactions of metals
Lesson 1 | Patterns in metal activity on the periodic table
-
analyse patterns in metal activity on the periodic table and explain why they correlate with, for example:
– ionisation energy (ACSCH045)
– atomic radius (ACSCH007)
– electronegativity (ACSCH057)
Lesson 2 | Reactivity of metals
-
conduct practical investigations to compare the reactivity of a variety of metals in:
– water
– dilute acid (ACSCH032, ACSCH037)
– oxygen
– other metal ions in solution -
construct a metal activity series using data obtained from practical investigations and compare this series with that obtained from standard secondary-sourced information (ACSCH103)
Lesson 3 | Oxidation states
-
apply the definitions of oxidation and reduction in terms of electron transfer and oxidation numbers to a range of reduction and oxidation (redox) reactions
-
construct relevant half-equations and balanced overall equations to represent a range of redox reactions
Lesson 4 | Galvanic cells
-
conduct investigations to measure and compare the reduction potential of galvanic half-cells
-
predict the spontaneity of redox reactions using the value of cell potentials (ACSCH079, ACSCH080)
-
predict the reaction of metals in solutions using the table of standard reduction potentials
