Which of the following hydrolysis statements are correct?

A $ICl$ hydrolyses to $HOI$ and $HCl$ .
B $IF X_{5}$ hydrolyses without any change in the oxidation state of iodine.
C $IF X_{7}$ hydrolyses without any change in the oxidation state of iodine.
D $ICl$ hydrolyses to $HOCl$ and $HI$ .

Answer: A, B, C

Iodine is +5 in

IF X_{5}

(giving

HIO X_{3}

) and +7 in

IF X_{7}

(giving

H X_{5} IO X_{6}

), so neither is a redox change. In

ICl

iodine is the positive end (+1), so hydrolysis gives

HOI

and

HCl

, not

HOCl

and

HI

.
