. Calculate the percentage degree of dissociation of an electrolyte
Calculate the percentage degree of dissociation of an electrolyte XY2 (Normal molar mass = 164) in water if the observed molar mass by measuring elevation in boiling point is 65.6
D: None of these
Dissociation of XY2 -
XY2 X + 2Y (n=3)
Where n is a sum of dissociated moles on the product side.
- Degree of dissociation
i - Van’t Hoff’s factor
n - Dissociated total moles on product side
To calculate Van’t Hoff’s factor-
i = normal molar massobserved molar mass
Percent degree of dissociation-
Hence, Option (A) is correct.
