Question

A solution of potassium nitrate, an electrolyte, and a solution of glycerin (C3H5(OH)3), a nonelectrolyte, both boil at 100.3°C. What other physical properties of the two solutions are identical?

Answer 1

A solution of potassium nitrate, an electrolyte, and a solution of glycerin (C3H5(OH)3), a non-electrolyte, both boil at 100.3°C. The other physical properties which are identical of both solutions are:

• Both form homogeneous solutions.

• Their boiling point elevations are the same,
• So the lowering of vapor pressures is also the same.

• Osmotic pressure and the lowering of the freezing point are also the same for both solutions.
