Chemistry-Solutions

TermDefinition
Suspension A solution that will settle out if left undisturbed, but is not homogeneous.
Colloid A solution that will not settle out.
Brownian Motion Random movements of colloid particles
Tyndall Effect Shining a light through a solution- if the light disperses then the solution is a colloid.
Soluble Dissolves in solvent
Miscible two substances dissolve in each other
Insoluble Does not dissolve in in solvent
Immiscible two substances that don't dissolve in each other
Concentration how much solute solute is dissolved in a specific amount of solvent or solution
Molarity number of moles of solute dissolved per liter of solution. (molar concentration) ( moles of solute/ Liters of solution)
Molality moles of solute dissolved in one Kg of solvent, ratio. (moles solute/ Kg solvent)
Mole fraction ratio of moles of solute to moles of solution
Solvation surrounding solute particles with solvent particles to form a solution.
Heat of solution overall energy change that occurs during the process of creating a solution
Unsaturated solution less dissolved solute, has capacity to hold more solute.
Saturated solution maximum amount of of dissolved solute
Supersaturated solution more dissolved solute than saturated solution at same temperature and pressure.
Henry's Law At a given temp. the solubility of the gas in a liquid is directly proportional to the pressure of the gas above the liquid.
Colligative property Physical property of a solution dependent on the number of dissolved solute particles.
Vapor pressure lowering lowering of vapor pressure of a solvent by adding a solute that does not evaporate.
Boiling point elevation Temp difference between solution's boiling point and pure solvent's boiling point
Freezing point depression Temp difference between solution's freezing point and pure solvent's freezing point.
Osmosis Diffusion of solvent particles across semipermeable membrane from high concentration to low concentration.
Osmotic pressure pressure caused by osmosis
Vapor pressure pressure exerted by a vapor over a liquid

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.
