Answer:- In order to determine freezing point of an aqueous solution, we label the solute in ionic form.
The above given solutes are:
K2CO3 -----> 2 K+ ions and 1 CO32- ion, total ions = 3.
NaNO3 -----> 1 Na+ ion and 1 NO3- ion, total ions = 2.
Li3PO4 -----> 3 Li+ ions and 1 PO43- ion, total ions = 4.
Solute with higher number of ions will have lower freezing point.
Thus, the order of highest freezing point to lowest freezing point would be:
NaNO3 (Highest F.P.)
K2CO3
Li3PO4 (Lowest F.P.)
