Q
what is a mono basic acid?
A
- 1H+ ion is replaced per molecule in an acid base reaction
- replacement is typically metal or ammonium ion
2
Q
give an example of a mono basic acid?
A
HCl
3
Q
what is a dibasic acid?
A
2 protons replaced in a reaction
4
Q
give an example of a dibasic acid?
A
H2SO4
5
Q
define ‘acid’
A
proton donor
6
Q
define ‘base’
A
proton acceptor
7
Q
describe HCl as a conjugate base pair
A
- in the forward direction, HCl releases a proton to form a conjugate base: Cl-
- in the reverse direction, CL- accepts a proton to form a conjugate acid: HCl
8
Q
what is the hydronium ion?
A
H3O+
9
Q
what do acids do in the presence of water?
A
- donate H+ ions
- forms H3O+
10
Q
what do bases do in the presence of water?
A
- accepts H+ ions
- forms OH-
11
Q
what is the pH of salts?
A
7 (neutral)
12
Q
acid + base –>
A
salt + water
13
Q
what are salts made from?
A
metal of base and non metal of acid
