Increases the volume of water
Explanation:
Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.
When ice freezes it expands and takes up more volume of space for the same mass given.
This is why bottles break when water in them is frozen.
This increase in volume is why ice floats on water. It makes it less dense.

Answer:
0.200 m K3PO3
Explanation:
Let us remember that the freezing point depression is obtained from the formula;
ΔTf = Kf m i
Where;
Kf = freezing point constant
m = molality
i = Van't Hoff factor
The Van't Hoff factor has to do with the number of particles in solution. Let us consider the Van't Hoff factor for each specie.
0.200 m HOCH2CH2OH - 1
0.200 m Ba(NO3)2 - 3
0.200 m K3PO3 - 4
0.200 m Ca(CIO4)2 - 3
Hence, 0.200 m K3PO3 has the greatest van't Hoff factor and consequently the greatest freezing point depression.
