The molal elevation constant $KThe freezing point of water is depressed when a non-volatile solute is added because:Osmotic pressure of a dilute solution is expressed by van't Hoff's equation as:Two solutions are said to be **isotonic** if they:If $\mathrm{NaCl}$ undergoes complete dissociation in water, the van't Hoff factor $i$ is:Benzoic acid associates in benzene to form dimers. The van't Hoff factor $i$ for benzoic acid in benzene (assuDesalination of sea water is best carried out by:A solution of glucose in water has a freezing point depression of $0.186\,\text{K}$. Given $K_f$ for water $= A solution showing positive deviation from Raoult's law has:
