Define osmosis and osmotic pressure and show that osmotic pressure is a colligative property. |
|
Answer» Solution :OSMOSIS and osmotic PRESSURE. Refer to brief review. Osmotic pressure `(pi)` for a DILUTE solution is given as `pi prop (n_B )/(V )`(At constant temperature) ` n_B= N o.` of moles of solute V = Volume of solution or volume of solvent because solution is dilute. ` thereforepi` depends UPON no. of moles of solute dissolved in a given amount of solvent and is independent of nature of solute particles, `THEREFORE` it is a colligative property. |
