slide10

The particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated

slide15

concentration (# of particles) of solute dissolved in the solution

slide16

Pure, unsweetened tea boils at 99.5°C. If 5 grams of sugar were dissolved in that tea and then the solution was brought to a boil, would the new boiling point be equal to, greater than, or less than 99.5°C?

slide18

In the winter, when trucks add salt to icy streets, what colligative property is being displayed?

slide20

What happens to the vapor pressure above a saltwater solution if an additional 25 grams of NaCl are dissolved into the solution?

slide21

The vapor pressure decreases; vapor pressure lowering

slide22

If a red blood cell is placed in a hypertonic solution, it will begin to shrivel. Which solution is more concentrated, the one inside of the cell or the one outside of the cell?

slide23

outside of the cell; according to osmosis, the water (solvent) moves from lower to higher concentration so it leaves the less concentrated blood cell and enters the more concentrated outside solution, causing the cell to shrivel

slide25

Molarity (M) = mol / L

Molality (m) = mol / kg

slide26

The molarity of a solution in which 48.5 grams of NaCl are dissolved in 0.50 liters of solution.

slide38

The type of solution found at 40⁰C, when 110 grams of NaNO3 is dissolved in 100 grams of water.

slide42

The amount of precipitate formed when a saturated solution of KNO3 is cooled from 60⁰C to 20⁰C.

slide52

In addition to surface area/particle size, what are the 3 other factors that affect the solubility of a solid in a liquid?

slide54

Final Jeopardy

Make your wager

slide55

Name the 6 substances that were mixed with water in the Types of Mixtures Lab we did for this unit.
