The walls of erythrocytes (red blood cells) are permeableto water. In a salt solution, they shrivel (lose water) whenthe outside salt concentration is high and swell (take upwater) when the outside salt concentration is low. In anexperiment at 25°C, an aqueous solution of NaCl that hasa freezing point of-0.046°C causes erythrocytes neitherto swell nor to shrink, indicating that the osmotic pressureof their contents is equal to that of the NaCl solution.Calculate the osmotic pressure of the solution inside theerythrocytes under these conditions, assuming that itsmolarity and molality are equal.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
