Acid-base titration

Acid-base titration. Titration. In an acid-base titration, a solution of unknown concentration ( titrant ) is slowly added to a solution of known concentration from a burette until the reaction is complete when the reaction is complete we have reached the endpoint of the titration

How Much Does the pH of a Buffer Change When an Acid or Base Is Added?

How Much Does the pH of a Buffer Change When an Acid or Base Is Added?. though buffers do resist change in pH when acid or base are added to them, their pH does change calculating the new pH after adding acid or base requires breaking the problem into 2 parts
