**Question: Osmolarity and Isotonic Solutions**The osmolarity of physiological saline solution is 0.300 osmol/L.**Problem:**Assuming a membrane that is permeable only to water, what % (w/v) zinc bromide, \( \text{ZnBr}_2 \), solution is isotonic to physiological saline?**Answer Box:**\[ \_\_\_\_\_\_\ \% \ (w/v) \]Note: * Osmolarity refers to the concentration of osmotically active particles in solution.* Isotonic solutions have the same osmolarity, hence no net movement of water occurs across the membrane.To determine the correct % (w/v) for an isotonic \( \text{ZnBr}_2 \) solution, calculations based on the dissociation of zinc bromide into its respective ions and the osmotic balance need to be performed.

The total number of solute particle per liter is known as osmolarity.

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.
