Question

classify each substance as a solution, a colloid, or a suspension. write each name in one of the boxes below. herbed salad dressing milk paint perfume smoke pulpy orange juice tea vinegar colloids suspensions solutions

Explanation:

• Colloids: A colloid is a mixture where small particles are dispersed throughout a medium, and they don't settle out. Milk (liquid - liquid colloid), paint (solid - liquid colloid), perfume (liquid - gas colloid), smoke (solid - gas colloid) fit this as their particles are dispersed and don't settle quickly.
• Suspensions: A suspension has larger particles that settle out over time. Herbed salad dressing (solid particles in liquid, settles), pulpy orange juice (pulp settles) are suspensions.
• Solutions: A solution is a homogeneous mixture where solute dissolves in solvent. Tea (solute dissolved in water), vinegar (acetic acid in water) are homogeneous solutions.

Answer:

• Colloids: milk, paint, perfume, smoke
• Suspensions: herbed salad dressing, pulpy orange juice
• Solutions: tea, vinegar
