Chemistry: Chpt 19

Acids and Bases

TermDefinition
Acid more hydrogen ions than hydroxide ions
Base more hydroxide ions than hydrogen ions
pH the negative log of the hydrogen-ion concentration 0-7 = ACID 7-14 = BASE pH = -log[H+]
pOH the negative log of the hydroxide-ion concentration 0-7 = BASE 7-14 = ACID pOH = -log[OH-]
indicator acids or bases that undergo dissociation at a known pH
end point the point at which the indicator changes color
acid ionization constant Ka = (products/acid)
amphoteric substances that can act as both acids and bases
base ionization constant Kb = (products/base)
Arrhenius model
Bronsted-Lowry model Acid is the proton donor and the base is the proton acceptor
conjugate acid
Neutralization a base combined with an acid to neutralize an aqueous solution
weak acid/base ionize only slightly in an aqueous solution (acetic acid and ammonia)
strong acid/base completely ionized in an aqueous solution (HCl and NaOH)
salt combining OH- and H+ to make water and using whatever is left over to make a salt
standard solution
Properties of acids 1. sour taste 2. astringent feel on skin 3. turn blue litmus paper red 4. combine with base to form a salt 5. H3O+
Properties of Bases 1. taste bitter 2. feel slimy 3. turn red litmus paper blue 4. combine with acid to form a salt 5. OH-
Identify A/B Pairs 1. Determine which compounds go together 2. Loses an H+ (acid/con. base) 3. Gains an H+ (base/con. acid) TIPS (+) = acid (-) = base **acid/base always on left of yield **conj. A/B always on right of yield

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.
