Question

solution (so), suspension (p), or colloid (c)? it settles suspension. doesnt settle or scatter light solution. scatters light, but doesnt settle colloid. can be filtered suspensions. homogeneous at molecular level so. particles sometimes visible colloid. 1. tyndall effect a. to lessen the concentration of a solution (add solvent). 2. supersaturated b. when a solution can hold more solute. 3. saturated c. when a solution cant hold more solute. 4. solute d. when a solution has more solute than it can hold. 5. unsaturated e. the part of the solution that dissolved. 6. solvent f. the scattering of light in a colloid. 7. dilute g. what is doing the dissolving. 50 ml of a solvent can hold 80 g of a solute, are the following saturated, unsaturated, or supersaturated? 35 g. 82 g 75 g 80 g 100 g 81 g which one is more concentrated? a 35% solution or a 46% solution? a supersaturated solution or a saturated solution? thin syrup or thick syrup? a saturated solution or an unsaturated solution? a diluted solution or an undiluted solution? a the colloid. b the solution. a a substance. b will settle. c can be separated physically. if the two pictures show what happens to a mixture after a time, what kind of mixture is it and why?

Explanation:

1. Matching terms with definitions

• Tyndall Effect is the scattering of light in a colloid, so 1 - F.
• Supersaturated is when a solution has more solute than it can hold, so 2 - D.
• Saturated is when a solution can't hold more solute, so 3 - C.
• Solute is the part of the solution that dissolved, so 4 - E.
• Unsaturated is when a solution can hold more solute, so 5 - B.
• Solvent is what is doing the dissolving, so 6 - G.
• Dilute is to lessen the concentration of a solution (add solvent), so 7 - A.

2. Classifying solutions as saturated, unsaturated or supersaturated

• Since 50 mL of solvent can hold 80 g of solute:
• 35 g of solute in 50 mL of solvent is an unsaturated solution as it can hold more solute.
• 82 g of solute in 50 mL of solvent is a supersaturated solution as it has more solute than it can hold.
• 75 g of solute in 50 mL of solvent is an unsaturated solution.
• 80 g of solute in 50 mL of solvent is a saturated solution.
• 100 g of solute in 50 mL of solvent is a supersaturated solution.
• 81 g of solute in 50 mL of solvent is a supersaturated solution.

3. Comparing concentrations

• A 46% solution is more concentrated than a 35% solution.
• A supersaturated solution is more concentrated than a saturated solution.
• Thick syrup is more concentrated than thin syrup.
• A saturated solution is more concentrated than an unsaturated solution.
• An undiluted solution is more concentrated than a diluted solution.

4. Identifying mixtures from diagrams

• The first set of diagrams: The one with larger particles that can be seen is a suspension. The one with very small - sized particles evenly distributed is a solution. The one with particles that scatter light but don't settle is a colloid.
• For the last question about the two - picture mixture: Since the particles settle over time, it is a suspension because suspensions are characterized by particles that settle out of the mixture upon standing.

Answer:

1. 1 - F, 2 - D, 3 - C, 4 - E, 5 - B, 6 - G, 7 - A
2. Unsaturated, Supersaturated, Unsaturated, Saturated, Supersaturated, Supersaturated
3. 46% solution, Supersaturated solution, Thick syrup, Saturated solution, Undiluted solution
4. Suspension because the particles settle over time.
