which statement accurately describes part of the dissolving process of a polar solute in water?
A. Water molecules surround solute particles.
B. Solute molecules repel water molecules.
C. Solute molecules remain concentrated in one part of the solvent.
D. Water molecules are strongly attracted to nonpolar substances.
Answer:- A. Water molecules surround solute particles.
The above option is the correct one due to a high solubility of sodium chloride, being amphipol solutes.
Water is a polar solvent due to partial negative charge on the oxygen atom and positive charges on hydrogen atoms. This makes it possible for water to directly contact with other polar molecules and ions. When the polar solute such as sodium chloride is put into water, slightly positive ions of sodium and partially negative ionic charges out of chlorine attracts toward opposite poles on molecules in this same direction. The oxygen ends of the water molecules are able to surround positively charged sodium ions, while their hydrogen parts can be oriented towards negatively charged chloride ions. This enables the ions to repel and dissociate in water.
The solute-solute interactions are therefore broken as a large number of water molecules surround and interact with the particles through ion-dipole interaction. The solute particles have begun to interact more strongly with the water molecules than with each other. This procedure enables the solute to dissolve in the solvent and distribute across this solution. It is thanks to the polarity of water that it dissolves polar solute molecules such as salts, sugars and acids by surrounding charged particles with their complementary opposite charges . This is why water is called the universal solvent because of its amphiphilic properties that make it dissolve many ion and polar covalent compounds.
