# What are the properties of acids and bases?

Apr 13, 2018

See below:

#### Explanation:

Acids:

1. Have a low $p H$
2. Are corrosive
3. Turns litmus paper red.

Bases:

1. Have a high $p H$
2. Are caustic/corrosive
3. Feel slippery to the touch
4. Turns litmus paper blue.

Classification of the chemical properties of acids and bases can be defined by two means, either as:

Bronstedt-Lowry acids/bases is defined in terms of protons:
A B-L base is a proton acceptor, i.e a species which accepts a proton from another species.
Conversely, a B-L acid is said to be a proton donor, which will "force" protons onto another chemical species.

Lewis Acids and bases are defined in terms of lone electrons pairs. A Lewis base is a species which donates a lone electron pair to another species. A Lewis acid is a species which can accept a lone pair of electrons from another species.

Hopefully, this helped!
