Term | Definition |
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 |
