Question

What is the equivalent weight of KH(IO3)2 as an oxidant in presence of 4.0 (N) HCl when ICI becomes the reduced from?

Solution

Correct option is

48.75

 

In KH(IO3)2, IO3 is present as state of I will be

                  x –6 = –1 or = + 5.  

                    +5                      +1

             KH (IO3)2            2ICl

Decrease in oxidation state = + 10 –2 = 8

Equivalent wt. of  

                                     = 48.75
