Acids and Bases Flashcards
1
Q
Arrenhius Acid
A
will dissociate to form an excess of H+ in solution
2
Q
Arrenhius Base
A
will dissociate to form an excess of OH- in solution
3
Q
BL acids and bases
A
H+ donors and acceptors
4
Q
Lewis acid and base
A
electron pair acceptor and donor
5
Q
amphoteric
A
reacts like an acid in basic environment and base in acidic environment
6
Q
examples of amphoteric species
A
- partially dissociated conjugate base of polyvalent acid
- water
7

A
H3PO4
8
Q
Boric acid
A
H3BO3
9
Q
chromic acid
A
H2CrO4
10
Q
water dissociation constant
A
Kw = [H3O+][OH-] = 10^-14
11
Q
pH
A
pH = -log[H+] = log 1/[H+]
12
Q
pOH
A
pOH = -log[OH-] = log 1/[OH-]
13
Q
pH + pOH
A
14
14
Q
relationship between pKa, pKb, pH, and pOH
A
pH = pKa + log([A-]/[HA])
pOH = pKb + log([salt]/[base])
15
Q
Ka
A
Ka = [H3O+][A-]/[HA]
