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

f.pt. is raised

f. pt. is lowered

f.pt. does not change

b.pt. does not change

Text Solution

Verified by Experts

The correct Answer is:

`2 KI + HgI_(2) rarr K_(2) HgI_(4)`. As a result of this reaction, no. of ions decrease. So the lowering in F pt. is less or the actual F. pt is more.
