what happens when u add salt in water

When salt (sodium chloride, NaCl) is added to water, it dissolves and dissociates into its constituent ions: sodium ions (Na⁺) and chloride ions (Cl⁻). This process occurs due to the attractive forces between the polar water molecules and the charged ions in the salt.
Here’s a step-by-step breakdown of what happens:
1. **Dissociation**: The ionic bonds between sodium and chloride ions in the salt are broken as water molecules surround the individual ions. The negative ends (oxygen) of water molecules are attracted to the sodium ions, while the positive ends (hydrogens) are attracted to the chloride ions.
2. **Solvation**: The water molecules form a shell around the separated ions, a process known as solvation. This helps keep the ions dispersed in the solution.
3. **Conductivity**: As the salt dissolves, the resulting solution becomes an electrolyte, meaning it can conduct electricity due to the presence of free-moving ions.
4. **Colligative Properties**: Adding salt to water also affects various properties of the solution, such as lowering the freezing point (freezing point depression) and raising the boiling point (boiling point elevation).
Overall, adding salt to water results in a homogeneous solution where the physical and chemical properties of the solution differ from those of pure water.
