QuestionAnswer
Hydration Combination with water
Solution Homogeneous mixture. A sample of matter consisting of more than one pure substance with properties that do not vary within the sample.
Aqueous Solution A substance dissolved in water
Solute A substance dissolved in a solvent to make a solution
Solvent The most abundant component in a solution. Usually water.
Electrolyte A substance that dissociates fully or partially into ions when dissolved in a solvent, producing a solution that conducts electricity.
Strong Electrolyte a solute that completely dissociates into ions in solution and conducts electricity.
Weak Electrolyte a solute that incompletely dissociates into ions in solution. Conducts a low amount of electricity
Nonelectrolyte a substance that does not ionize in a solution or conduct any electricity
Acid a compound containing detachable hydrogen ions
Strong Acid an acid that completely dissociates into hydrogen ions and anions in solution. A strong electrolyte
Weak Acid An acid that only partially dissociates into hydrogen ions and anions in solution.
Weak Base A weak electrolyte that only partially dissociates into ions in solution
Molarity Molar concentration
Standard Solution A solution of precisely known concentration
Dilution Adding solvent to a solution to lower its concentration
Precipitate An insoluble substance that has been formed from substances dissolved in a solution
Soluble Capable of being dissolved in a solvent
Insoluble a substance that does not dissolve in a solvent to any significant degree
Spectator Ions an ion that appears as both a reactant and a product in an ionic equation
Equivalence Point the point in a titration when enough titrant has been added to react completely
Indicator A substance that undergoes an sharp, easily observable change when conditions in its solutions change
Endpoint The experimental estimate of the equivalence point in a titration
Oxidation the loss of one or more electrons by an atom, molecule, or ion.
Reduction the gain of one or more electrons by an atom, molecule, or ion
REDOX A reaction that involves transfer of electrons from one substance to another
Oxidation State A convention for representing a charge of an atom embedded within a compound

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.
