Answer:A common example would be salt added to water. ... For example, in the salt example, the water molecules must be able to interact with each ions. Stirring exposes more of the solute, and makes more of the solute come in contact with the solvent, thus increasing the rate of dissolution.

Answer:
When salt is mixed with water, the salt dissolves because the water's covalent bonds are stronger than the salt molecules' ionic bonds.
Explanation:
- Salt dissolves in water due to electrical charges at the molecular level. Water and salt compounds are both polar molecules, containing positive and negative charges on opposite surfaces. Ionic bonds exist in salt compounds because both the chloride and sodium ions have an electrical charge—the chloride ion is negatively charged, while the sodium ion is positively charged. A water molecule is also ionic in nature. Even so, the connection is considered covalent because two hydrogen atoms are positioned with their positive charges on one side of a negatively charged oxygen atom.
- The negatively charged chloride ions attract the positively charged side of the water molecules. The positively charged sodium ions attract the negatively charged side of the water molecules.
- The ionic bond that held the sodium and chloride ions together is broken when water molecules pull them apart.
- The sodium and chloride atoms are surrounded by water molecules once the salt compounds are separated. The salt is dissolved at this point, resulting in a homogenous solution.
