However, stearic acid is highly soluble in organic solvents such as ethanol, ether, chloroform, and other nonpolar solvents. When added to water, stearic acid tends to form aggregates or micelles, where the hydrophilic carboxylate groups are exposed to water while the hydrocarbon chains remain shielded, reducing their contact with water molecules. This behavior contributes to the limited solubility of stearic acid in water.
What is the formula of stearic acid?
Stearic acid has the molecular formula C18H36O2. It is made up of a long hydrocarbon chain with 18 carbon atoms (C18) and two oxygen atoms (O2) joined by a carboxyl group (-COOH). The hydrocarbon chain is entirely saturated with hydrogen atoms and only has single bonds connecting its carbon atoms. At room temperature, stearic acid has a solid, waxy form as a result of its saturation. It looks as a white solid in solid form and smells mildly unpleasant and oily. Stearic acid has an acidic nature thanks to the carboxyl group at the end of the hydrocarbon chain.
What is the stearic acid structure?
18 carbon atoms are organized in a straight line to form a lengthy hydrocarbon chain that makes up the linear structure of stearic acid. Due to the maximum number of hydrogen atoms being attached to each carbon atom, this saturated hydrocarbon chain only contains single bonds throughout.
The normally symmetrical chain is devoid of double bonds and branches. The overall structure of stearic acid can be imagined as a rigid, straight chain of carbon atoms connected to hydrogen atoms, with the carboxyl group at one end. Stearic acid has special capabilities due to its structure, such as the capacity to operate as a fatty acid in a variety of industrial and biological processes.
What is the pH of stearic acid?
Stearic acid is a weak acid due to its fatty acid nature. The concentration of stearic acid as well as the other components in the solution has an impact on its pH. When stearic acid is pure, it does not completely dissociate in water, leaving behind a low concentration of hydrogen ions (H+) and a somewhat acidic pH. However, the exact pH value may alter depending on variables like temperature, concentration, and the presence of additional acids or bases. Stearic acid typically has a pH of 4-6, regarded as acidic.
