What happened to the particles of salt dissolve in water ?

Question

Answer

The salt particles get dissolve in water. as we know water is a liquid and the kinetic energy between the particles is less as compared to that of solids, so the space between the particles of water is more and when we add salt in water the particles of salt go in between the spaces present in between the particles of water and hence it becomes a homogeneous mixture.

Answer

The kinetic energy of the particles of water is more as compared to the solids. So there is  space between the particles of the liquid. And, when we dissolve salt in water then the particles of salt settle between those space.

Answer

What happens to the particles of salt when they dissolve in water?

When salt (sodium chloride, NaCl) dissolves in water, the salt particles undergo a process called dissolution. This process involves the separation of the individual sodium and chloride ions from the crystal lattice structure of the salt and their dispersion throughout the water molecules.

Key Points:
- Dissolution is a physical process where the solute particles separate and disperse in a solvent.
- Salt particles are made up of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-).
- Water molecules are polar, with a slight positive charge on the hydrogen atom and a slight negative charge on the oxygen atom.
- The polar nature of water molecules allows them to interact with the charged ions of salt.

Process of Dissolution:
1. Separation of Salt Particles: When salt is added to water, the water molecules surround and interact with the salt crystals. The electrostatic attraction between the positive sodium ions and negative chloride ions is gradually weakened as water molecules pull the ions away from the crystal lattice structure.

2. Dispersal of Ions in Water: As water molecules surround the separated ions, they form hydration shells. The oxygen atom of water molecules interacts with the sodium ions, while the hydrogen atoms interact with the chloride ions. This process is known as hydration.

3. Ion Dispersal throughout the Solution: The dispersed sodium and chloride ions become evenly distributed throughout the water, creating a solution of saltwater. The ions are free to move within the solution due to the random motion of water molecules.

Key Takeaways:
- Dissolution of salt in water involves the separation of sodium and chloride ions from the crystal lattice structure and their dispersion in water.
- The polar nature of water molecules allows them to interact with the charged ions of salt.
- The process of dissolution results in the formation of a saltwater solution where the ions are evenly dispersed throughout the water.
