Explanation:

• The solute is the substance that is being dissolved, while is the dissolving part. For example, a solution of salt and water, has water as the solvent and salt as the solute.
• Solubility is the ability of a substance(Solute) to form a solution with another substance(Solvent). For example, sugar in water and salt in water.
• The Tyndall effect is the scattering of light as a light beam passes through a Colloid. The examples are Milk, Mayonnaise, Smoke, Fog, Sprays, etc.
