Looking at its morphology, under normal circumstances, it is mostly white to slightly yellow powder or crystalline. The formation of this morphology is related to many factors such as intermolecular interactions and crystallization conditions. Its color is lighter, reflecting the characteristics of light absorption by groups in the molecular structure.
When it comes to solubility, in water, the substance exhibits a certain degree of solubility. This is because its molecular structure contains polar groups such as sulfonic acid groups, which can form hydrogen bonds with water molecules and interact, so it can be dissolved in water to a certain extent. In organic solvents, such as common polar organic solvents such as methanol and ethanol, it also has good solubility. This is due to the principle of similar miscibility, and the interaction between polar solutes and polar solvents is conducive to dissolution. However, in non-polar organic solvents, such as n-hexane, its solubility is poor.
In addition to the melting point, the substance has a specific melting point value. The melting point depends on the strength of the intermolecular force. There are many fluorine atoms in the molecule, which enhances the intermolecular van der Waals force. Coupled with the action of ionic bonds, the melting point is relatively high. Accurate determination of the melting point is of great significance for identifying the substance and judging its purity.
Its density is also an important physical property. The size of the density is related to the weight of the molecule and the degree of molecular accumulation. The existence of many fluorine atoms increases the molecular weight, and the specific molecular structure determines the molecular accumulation mode, and the specific density value is formed under the comprehensive action.
In addition, the stability of the substance is also an important consideration of physical properties. Due to the high bond energy of the fluorine atoms in the molecule, it endows the substance with good chemical stability. Under normal conditions, it is not easy to decompose and deteriorate, which can maintain the relative stability of its chemical structure and properties.
