QuestionAnswer
Le Châtelier’s principle when a chemical system at equilibrium is disturbed, it reacts in a way to counteract the disturbance.
Arrhenius acid a substance that produces H+ ions in aqueous solution.
Arrhenius base a substance that produces OH− ions in aqueous solution.
hydronium ion H3O+, the ion formed from the association of a water molecule with an H+ ion donated by an acid.
Bronsted-Lowry acid a proton ( H+ion) donor.
Bronsted-Lowry base a proton acceptor.
conjugate acid-base pair Two substances related to each other by the transfer of a proton.
Strong base A base that completely dissociates in solution.
weak acid An acid that does not completely ionize in water.
Weak base A base that only partially ionizes in water.
acid ionization constant(Ka) The equilibrium constant for the ionization reaction of a weak acid; used to compare the relative strengths of weak acids.
Autoionization The process by which water acts as an acid and a base with itself.
ion product constant for water or dissociation constant for water The equilibrium constant for the autoionization of water.
acidic solution A solution containing an acid that creates additional H3O+ ions, causing [H3O+] to increase. [H3O+] is greater than 1.0 x 10^-7M
basic solution A solution containing a base that creates additional OH− ions, causing the [OH−] to increase. [H3O+] is less than 1.0 x 10^-7M
pH The negative log of the concentration of H3O+ in a solution; the pH scale is a compact way to specify the acidity of a solution.
pOH the negative log of the concentration of [OH−]; the pOH scale is analogous to the pH scale.
Lewis acid An atom, ion, or molecule that is an electron pair acceptor.
Lewis base An atom, ion, or molecule that is an electron pair donor.
strong acid An acid that completely ionizes in solution.
Endothermic Reaction A chemical reaction that absorbs heat from its surroundings; for an endothermic reaction, ΔH > 0.
Exothermic Reaction A chemical reaction that releases heat to its surroundings; for an exothermic reaction, ΔH < 0.

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.
