TermDefinition
solution a homogeneous mixture
solvent the part of solution that does the dissolving (greater amount)
solute the part of a solution that is being dissolved (lesser amount)
miscible "mixable", "like dissolves like"
immiscible not mixable - oil and water
salvation when the solvent surrounds the solute
hydration when water is the solvent & surrounds the solute
solubility the ability to be dissolved - a numerical value
unsaturated when the solvent is able to dissolve more solute
saturated when the solvent is completely full of solute
supersaturated when the solute "falls out" of the solution bcs too much is added
henry's law gases stay dissolved in solutions when pressure is high
effervescence gases/bubbles leaving a solution
concentration a measure describing the solute/solvent ratio (molarity and molality)
molarity M = mol/L; moles of solute per liters of solution
molality m = mol/kg; moles of solute per kg of solvent
colligative properties the new properties of a substance after a solute is added a solvent
osmosis the movement of water through a semipermeable membrane
colloid the solute particles remain suspended in solution bcs they are light
3 steps of the dissolving process 1. dissociation - solute particles separate 2. solvation/hydration - solvent particles surround solute 3.diffusion - solute moves throughout w brownian motion (molecular motion)
what are the 4 colligative properties of solutions? 1. decrease vapor pressure 2. incrase boiling point 3. decrease freezing point
what 2 factors affect solubility? pressure and temp
what are 3 factors that affect the rate of solution? stirring, surface area, temp

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
