Principle

Buffer solutions usually consist of weak acids and their conjugate bases. Acids neutralise hydroxide-ions, bases on the other hand oxonium-ions. A buffer solution is produced by adding an equimolar mixture of a weak acid and its salt (e.g. acetic acid and sodium acetate) or a weak base and its salt (e.g. ammonium chloride and ammonia).

In this experiment student examin a buffer solutions (here: acetate buffer) and how they work by adding a strong base (here: sodium hydroxide solution) to such.
