converting floride to florine required a reduction.
you cannot convert floride and water into florine by boiling it.
water also contains bleach and chlorine. These are oxidative when boiled which is the opposite process needed if you wanted to convert floride into florine.
PLEASE REMOVE THIS. IT IS FALSE.
Have done; had doubts but thought the person who passed it on was knowledgeable. Now I know better.
All good! Thanks!
