Some Sodium Chloride salt is dissolved in water. Some of the salt dissolves. While some other salt settles at the bottom of the chemical tube. When viewed on an atomic scale, the dissolved salt is in the form of Na⁺ ions and Cl⁻ ions. The salt that settles is in the form of NaCl molecules. In further analysis, salt ions and salt molecules form an equilibrium reaction. When NaCl molecules ionize into Na⁺ ions and Cl⁻ ions, at the same time Na⁺ ions and Cl⁻ ions form NaCl molecules. This process causes the ions dissolved in water to have the same amount.
