The alkalinity is mainly due to hydroxide, carbonates and bicarbonate ions in the water. Other anions (to a lesser extent) also lead to hydrolysed alkalinity phosphates, silicates, borates, fluorides and salts of organic acids. The Hanna test kit determines the phenolphthalein alkalinity (= TAP or TA) as well as the total alkalinity (TAM or TAc, or bicarbonate hardness) in the water by a titrimetric method. For TAP, titration is carried out to pH 8.3 (hydroxide ions and half of the carbonates). At total alkalinity (= TAM or bicarbonate hardness) is titrated to pH 4.5 (all hydroxide ions, carbonates and bicarbonates). The chemical products are safe to use in household and industrial conditions.
