Question

Molecular weight of KMnQ is "M". In a
reaction KMnQ is reduced to K,MnO.
The equivalent weight of KMnO is​

Answer 1

Equivalent weight is = M/6.

Explanation:

The molecular formula of POTASSIUM BROMATE is KBrO_3KBrO _3

It is also written as BrKO_3BrKO_3

It refers to potassium salt and a bromate salt.

Molecular Weight is measured as 167 g/mol.

Given that,

Molecular weight of KBrO_3KBrO 3 is M.

The chemical reaction in acidic medium:

BrO_3 ^- - > Br^-BrO

(Acidic medium)

Oxidation state of Br in BrO_3 ^-BrO

n =[5 - (- 1)] = 6n=[5−(−1)]=6

We know that,

Equivalent weight = (Molecular weight)/n

= M/6

Hence, Equivalent weight is = M/6.
