Question

25 match the following examples with the correct answer. choices may be used more than once. — witch hazel i a. emulsion — shampoo b. suspension — calamine lotion c. solution — mayonnaise — conditioner — paint

Explanation:

To solve this, we analyze each substance based on the definitions of solution, suspension, and emulsion:

• Witch hazel: A homogeneous mixture (solute dissolved in solvent), so it is a solution (c).
• Shampoo: Typically an emulsion (mixture of oil and water with emulsifiers), so it is an emulsion (a).
• Calamine lotion: Contains solid particles dispersed in a liquid (settles over time), so it is a suspension (b).
• Mayonnaise: A classic emulsion (oil dispersed in water with egg yolk as emulsifier), so it is an emulsion (a).
• Conditioner: Often an emulsion (mix of oils and water), so it is an emulsion (a).
• Paint: Contains solid pigment particles dispersed in a liquid (settles), so it is a suspension (b).

Final Matches:

• witch hazel: c. solution
• shampoo: a. emulsion
• calamine lotion: b. suspension
• mayonnaise: a. emulsion
• conditioner: a. emulsion
• paint: b. suspension
