What can happen to a weak acid?

It can partially dissociate into ions andform an equilibrium

Why is a titration useful?

It can shows a concentration of a substance, identify substances and show the purity of a substance

What is the definition of an amphoteric substance?

Substances that can acts as either an acid or base

What is the definition of neutralisation?
