When $I_2$ is passed through $KCl$,$KF$,and $KBr$ solutions,what happens?

Which of the following substances is the strongest fluoride ion acceptor?

Which of the following is prepared by the electrolytic method?

Which of the following statements is not true for halogens?

Given below are two statements:
Statement $I$: The increasing order of boiling point of hydrogen halides is $HCl < HBr < HI < HF$
Statement $II$: The increasing order of melting point of hydrogen halides is $HCl < HBr < HF < HI$
In the light of the above statements, choose the correct answer from the options given below

Justify,by giving reactions,that among halogens,fluorine is the best oxidant and among hydrohalic compounds,hydroiodic acid is the best reductant.
