(14) which of the following aq. soln has highest boiling point? @0.1m NaclⒸ 0.01m Naz Poy ⑥0.2m Ba(NO3)2 0.03 m KN03. ​

The boiling point of a solution is determined by the number of solute particles in the solution. This is known as boiling point elevation, which is a colligative property. The more solute particles, the higher the boiling point.

1. NaCl is a strong electrolyte and will dissociate into 2 ions (Na+ and Cl-) in solution.
2. Na3PO4 will dissociate into 4 ions (3 Na+ and 1 PO4^3-) in solution.
3. Ba(NO3)2 will dissociate into 3 ions (1 Ba2+ and 2 NO3-) in solution.
4. KNO3 will dissociate into 2 ions (K+ and NO3-) in solution.

Now, we calculate the total concentration of ions for each solution:

1. NaCl: 0.1 M * 2 = 0.2 mol/L
2. Na3PO4: 0.01 M * 4 = 0.04 mol/L
3. Ba(NO3)2: 0.2 M * 3 = 0.6 mol/L
4. KNO3: 0.03 M * 2 = 0.06 mol/L

From these calculations, we can see that the 0.2 M Ba(NO3)2 solution has the highest total concentration of ions, and therefore, it will have the highest boiling point.
