Question

Fluorine decomposes cold water to give

A. $$4{H^ + } + 4{F^ - }\,{\text{and}}\,{O_2}$$  
B. $$HF\,{\text{and}}\,{H_2}$$
C. $$HF\,{\text{only}}$$
D. $${H_2}{F_2}\,{\text{and}}\,HF{O_4}$$
Answer :   $$4{H^ + } + 4{F^ - }\,{\text{and}}\,{O_2}$$
Solution :
$$2{F_2} + 2{H_2}O \to 4{H^ + } + 4{F^ - } + {O_2}$$
