1
Q
Acids
A
pH 1-6
Excess of H3O+ ions
Proton (H+) donors
Turns litmus red
2
Q
Bases
A
pH 8-14
Excess of OH- ions
Proton (H+) acceptors

Q
Strong Acids/Bases
A
Further from 7 on pH scale Larger amount of H3O+/OH- ions Faster rates of reaction Good conductors of electricity Fully dissociate
4
Q
Weak Acids/Bases
A
Closer to 7 on pH scale Lesser amount of H3O+/OH- ions Slower rates of reaction Poor conductors of electricity Partially dissociate

25
Equations for Strong Acids
```
pH = -log[H3O+]
[H3O+] = 10^-pH
```
26
Equations of Strong Bases
```
Kw = [OH-][H3O+]
[H3O+] = Kw/[OH-}
[OH-] = Kw/[H3O+]
```
