HgO is analysed by reaction with iodide ...

HgO is analysed by reaction with iodide and them titrating with an acid. The equivalent mass of `HgO` is `H_(2)O+HgO+4I^(-)rarrHgI_(4)^(-2)+2OH^(-)`

A

M

B

M/2

C

M/4

D

M/3

Text Solution

Verified by Experts

The correct Answer is:
B
`E=(M)/(n-f)`
`Hg^(+2)rarrHg^(+2)`
hence treating it as a salt, `n-f=2`
