Titration

Titration can be applied to determine HCO₃^- and CO₃^2- and also hardness in water.

Equipment

• Titration system Titrino 716 DM (Metrohm, Germany) for the determination of HCO₃^- and CO₃^2- in water
• Digital burette Solarus (Hirschmann, Germany) for the determination of water hardness

Sample preparation

A sample volume of at least 100 ml water is required for the determination of HCO₃^- and CO₃^2- (if less volume is available please contact Dr. Dirk Merten in advance). For the determination of hardness of water up to 100 ml of water are necessary (depending on the origin of the water).

It is not necessary to filtrate samples and acidification of samples is not permitted.
