New cards
arrhenius theory
acid donate \[H+\] and base donate \[OH-\]
2
New cards
bronsted-lowry theory

slightly
6
New cards
a weakly bonded hydrogen makes a ____ acid
strong
7
New cards
a strongly bonded hydrogen creates a ____ acid
weak
8
New cards
oxacids
acids that contain hydrogen, oxygen, and another element
9
New cards
strength of oxacids is determined by…
electronegativity of central atom and amount of oxygens per hydrogens in formula
10
New cards
polyprotic acids
acids that ionize more than once
11
New cards
anhydrides
acidic and basic anhydrides are compounds that become common acids and bases when added to water
12
New cards
neutralization reactions
occur when acids and bases react; produces a salt and water
13
New cards
amphiprotic
substance that both gains and loses protons
14
New cards
amphoteric
substance that can act as an acid and a base
15
New cards
Kw
autoionization constant of water
16
New cards
pH equation
pH = -log\[H+\]

Buffer solution
weak acid or base with it’s salt
20
New cards
Henderson-Hasselbalch equation
pH = pKa + log(\[A-\] /\[HA\])
