Titer of H2SO4 using Na2CO3 as per European Pharmacopoeia EP |
H2SO4 also known as oil of vitriol is described as the king of chemicals because of its versatility and high reactivity. Owing to its versatility it is used extensively in industries and therefore its titre determination is a frequent process. European Pharmacopoeia describes the method for titer determination of H2SO4 using Na2CO3 with colorimetric titration using a color indicator. This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation and method, changes can be made using the given method as a reference. Reaction: 1) 1st EQP: H2SO4 + Na2C03 → NaHCO3 + NaHSO4 2) Heating 3) 2nd EQP NaHCO3 + NaHSO4 →H2O + CO2 + Na2SO4 It is observed that for higher concentration without heating the solution after the first equivalence point, carbon dioxide was evolved and second equivalence point was detected. The application has been developed for the use of a potentiometric sensor instead of color indicator as given by the original method for colorimetric titration. |

In this reaction water is released as a byproduct. R-CO-R + 2CH3OH → RC(OCH3)2-R + H2O To avoid this side reaction, special reagent called K-reagent is used. Ketones form a major constituent of paints, lacquer, explosives etc. These ketones should be completely free from water. The water content has to be detected precisely before ketones are further used. This application note demonstrates volumetric Karl Fisher titration for the detection of water in ketones.
