IPT Acidity M

Titration with sodium hydrate

0,5 °f (on 10 ml)

625 °f

Acidity m is a measurement of the number of mineral acids contains in water. It is measured by titration with sodium hydrate, against the indicator m (originally methyl orange). It is usual to speak of acidity m (lowercase m) when the result is expressed in epm (equivalents per million) and acidity M (capital M) when the result is expressed in °f (French degrees) or in ppm CaCO3. In Germany, acidity m is also called “-m value”, or else negative m value, in Anglo-Saxon countries is called FMA (Free Mineral Acidity) and in France TAF (Titre en Acides Forts libres).

• 1 test tube 20ml
• Instructions

- The classic indicator (methylorange) has been replaced by our “indicator m”, which has a much better color change at the end point.
- IPT kits are ideal when few analyses are needed, with fair accuracy. For many analyses and higher precision, we recommend the HYDROCHECK kits, which also offer a lower cost per analysis.
