When mercuric iodide is added to the aqueous solution of potassium iodide, then:

A

freezing point is raised

B

freezing point is raised

C

freezing point is lowered

D

freezing point does change

Text Solution

Verified by Experts

The correct Answer is:
A
`8T_(b)=iK_(b)m`
`0.323=ixx3.9xx(0.5143xx1000)/(MW xx 35)`
`i=0.733`
`i=("observation")/("calculated MW")`
Calculated `MW = (130)/(0.733)=177.42`
