Question

Define: (i) Osmotic pressure (ii) Ebullioscopic constant.

✓

Answer

Osmotic pressure:
The excess of pressure on the side of the solution, that stops the net flow of solvent into the solution through a semipermeable membrane is called osmoticpressure.
Ebullioscopic constant:
Ebullioscopic constant or Molal elevation constant is the elevation in the boiling point produced when one mole of the solute is dissolved in one kilogram of solvent.
