→ Strong acid → Strong base → Weak acid → Weak base → Mixture of strong base/ weak base → Mixture of strong acid/ weak base → Mixture of strong acid/ weak base → Mixture of strong base/ weak acid → Buffer → Titration strong base by strong acid → Titration strong acid by strong base → Titration weak acid by strong base → Titration weak base by strong acid
The calculations are made by a strict method by means of - the electroneutrality - the conservation of matter, - the ionic product of water, - the acidity or basicity constants
