Activity 1 Describe the observable characteristics or properties of common solutions found at home or in sari-sari store or grocery Present the data gathered in table form to show the different properties of common solutions

Solutions are homogeneous mixtures, meaning, they have uniform appearance are composed of two parts: solute and solvent solute – lesser amount solvent – greater amount

Which is the solute? Solvent? Sample 1: Sugar solution Sample 2: Alcohol in water

Are solutions always liquid? Sample 1: Spoon Sample 2: Air

Naturally Occurring Solutions Seawater Rainwater Air

Manufactured/Processed Solutions Vinegar Gasoline Metal alloy Steel Brass Wine / liquor Brewed coffee Tea

True or False? Solutions have uniform appearance. Solute is the part of a solution that is greater in amount. In a salt solution, water is the solute. Solutions can be solids, liquids or gases. Solutions can be naturally occurring or manufactured.
