Question

Question 8.4 Fluorine reacts with ice and results in the change:

H2O(s) + F2(g)→HF(g) + HOF(g)

Justify that this reaction is a redox reaction.

Answer 1

H2O + F2 ---> HF + HOF

oxidation number of F in F2 = 0
oxidation number of F in HF = -1
oxidation number of F in HOF = +1

Here,we see oxidation number of FE decreases from zero to -1(HF) and increase from +1(HOF). This shows that F2 is both reduced as well as oxidised. hence, it is a redox reaction and more specifically , it is a disproportionation redox reaction.
