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?
