The formation of sodium chloride from sodium and chlorine is an
example of a simple Redox reaction. This reaction is displayed
below.
2Na(s) + Cl2(g) → 2NaCl(s)
Explain (with reference to changes in oxidation states) why this
is a Redox reaction and again with reference to it, explain what
is meant by the terms ‘reducing agent’ and ‘oxidising agent’.
