Explain on the basis of standard reduction potentials, fluorine is a strong oxidising agent while potassium is a strong reducing agent.

Explanation

(1) Fluorine has very high standard reduction potential (positive reduction potential).
(2) It has a strong tendency to accept electrons and get reduced.
(3) Hence, fluorine is a strong oxidising agent.
(4) Potassium has very low reduction potential (negative reductin potential).
(5) It has a strong tendency to donate electrons and get oxidised.
() Hence, potassium is a strong reducing agent.
