In this lesson we discuss the concept of redox processes from reduction and oxidation reactions, half equations, ionic equations and how to determine oxidation states (oxidation numbers). This is lesson eighteen in our physical chemistry series for Unit 6: Electrochemistry (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).
LESSON OBJECTIVE: Understand and explain redox reactions in terms of electron transfer and oxidation numbers.
LEARNING OUTCOMES (taken from the Cambridge International AS and A Level Chemistry (9701) 2019-2021 curriculum):
6.1 Redox processes: electron transfer and changes in oxidation number (oxidation state)
a) calculate oxidation numbers of elements in compounds and ions
b) describe and explain redox processes in terms of electron transfer and changes in oxidation number
