Acid-Base Theories

The Arrhenius theory
ACID: Substance that produces H+1 in water.
BASE: Substance that produces OH-1 in water.
Acids are substances which produce hydrogen ions in solution.
Bases are substances which produce hydroxide ions in solution.
Neutralisation happens because hydrogen ions and hydroxide ions react to produce water.

An acid is an electron pair acceptor.
A base is an electron pair donor.

The relationship between the Lewis theory and the Bronsted-Lowry theory is easiest to see
the relationship by looking at exactly what Bronsted-Lowry bases do when they accept
hydrogen ions. These Bronsted-Lowry bases of hydroxide ions and…
