Chem II

QuestionAnswer
a mixture containing particles that settle out if left undisturbed. Suspension
a heterogeneous solution of intermediate-sized particles. Colloid
the erratic movement of colloid particles. Brownian motion
the scattering of light by dispersed colloid particles. Tyndall effect
a substance that dissolves in a solvent. Soluble (write out)
two liquids that are soluble in each other in any proportion. Miscible (write out)
two liquids that can be mixed together but separate shortly after. Immiscible (write out)
a substance that does not dissolve in a solvent. Insoluble (write out)
a measure of how much solute is dissolved in a specific amount of solvent or solution. Concentration
the number of moles of solute dissolved per liter of solution. Molarity (write out)
the ratio of the number of moles of solute dissolved in 1 kg of solvent. Molality (write out)
the ratio of the number of moles of solute in solution to the total number of moles of solute and solvent. Mole fraction
the process of surrounding solute particles with solvent particles to form a solution. Solvation
the overall energy change that occurs when a solution forms. Heat of solution
states that at a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Henry's law
the amount of additional pressure caused by water molecules that move into a concentrated solution. Osmotic pressure
the diffusion of a solvent through a semipermeable membrane from areas of lower solute concentration to areas of higher solute concentration. Osmosis

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.
