Detailed explanation-1: -While it’s true that when a crystal of the ionic substance sodium chloride is dissolved in water the sodium and chloride ions separate from one another, they do not separate to form lumps of sodium metal or to form chlorine gas. Rather, they remain as single Na+ and Cl− ions, surrounded by water molecules.
Detailed explanation-2: -For sodium chloride, the Na+ ion becomes surrounded by the negative side of multiple water molecules and the Cl-ions are surrounded by the positive side of multiple water molecules. This interaction is called an ion-dipole intermolecular force, which is considered one of the strongest.
Detailed explanation-3: -Ionic bonding in sodium chloride. An atom of sodium (Na) donates one of its electrons to an atom of chlorine (Cl) in a chemical reaction, and the resulting positive ion (Na+) and negative ion (Cl−) form a stable ionic compound (sodium chloride; common table salt) based on this ionic bond.
Detailed explanation-4: -Question: How does table salt (NaCl) ( N a C l ) dissolve in water? A. Water molecules hydrogen bond with sodium ions and chloride ions.
