Answer:1. SaltwaterSolute: Salt (sodium chloride)Solvent: WaterWhy it’s a solution: Salt dissolves completely in water, forming a homogeneous mixture where the salt particles are evenly distributed at the molecular level.2. Sugar dissolved in teaSolute: SugarSolvent: Tea (mostly water)Why it’s a solution: The sugar molecules dissolve uniformly in the tea, so you cannot see separate sugar particles.3. AirSolute: Oxygen, carbon dioxide, other gasesSolvent: Nitrogen (major component)Why it’s a solution: Air is a mixture of gases where the different gases are evenly mixed and cannot be separated by simple physical means.4. VinegarSolute: Acetic acidSolvent: WaterWhy it’s a solution: Acetic acid molecules are evenly dispersed in water, creating a clear, uniform liquid without visible separation.5. Rubbing alcohol (Isopropyl alcohol in water)Solute: Isopropyl alcoholSolvent: WaterWhy it’s a solution: Isopropyl alcohol mixes evenly with water to form a single-phase, clear liquid solution.
