Vedclass · Answer

(A) The osmotic pressure $(\pi)$ is a colligative property given by the formula $\pi = iCRT$,where $i$ is the van't Hoff factor,$C$ is the molar concentration,$R$ is the gas constant,and $T$ is the temperature.Since all solutions have the same molar concentration $(1 \ M)$,the osmotic pressure depends on the van't Hoff factor $(i)$.$NaCl$ is a strong electrolyte that dissociates into two ions ($Na^+$ and $Cl^-$),so $i = 2$.Urea,sucrose,and glucose are non-electrolytes,so their van't Hoff factor $i = 1$.Since $NaCl$ has the highest van't Hoff factor,it will exhibit the highest osmotic pressure.

Which of the following solutions has the highest osmotic pressure?
