Stearic Acid Solubility in Hexane
On the solubility of stearic acid to n-hexane
, it is related to its properties. Stearic acid has a long-chain alkyl group, a carboxyl group at one end is hydrophilic, but the alkyl group is long and lipophilic, and the whole is more lipid-soluble. N-hexane, a non-polar organic solvent, is similar to the alkyl phase of stearic acid with its non-polar nature.
View The dissolution of stearic acid in n-hexane, the two attract each other due to intermolecular forces. There is a dispersion force between the non-polar molecules of n-hexane and the alkyl groups of stearic acid. Although this force is weak, many molecules interact to gradually disperse stearic acid molecules in n-hexane. And although the carboxyl group of stearic acid is polar, the long-chain alkyl group dominates its properties, so that it can obtain a certain solubility in non-polar n-hexane.
For the experiment, take an appropriate amount of stearic acid and put it in the container containing n-hexane. At first, stearic acid sinks to the bottom, and after stirring or heating, the stearic acid molecule is energized, the movement intensifies, and gradually mixes with n-hexane molecules. Over time, it can be seen that stearic acid dissolves in n-hexane, and the solution is clear and transparent.
Temperature has an effect on its solubility. When heating up, the kinetic energy of the molecule increases, and the movement of stearic acid and n-hexane molecules is dramatic, making it easier to intersperse and mix with On the contrary, the molecular kinetic energy decreases, the interaction weakens, and stearic acid may precipitate in solution.
In summary, stearic acid and n-hexane have solubility due to intermolecular forces and structural similarity, and are affected by factors such as temperature. This is a common way for substances to dissolve.
