Which method is chosen depends primarily on the water content that the sample is expected to have. Making the right choice is vital for obtaining reliable and reproducible results. Carl ROTH offers compatible reagents for both of these methods.
CH3OH + SO2 + RN → [RNH]SO3CH3
In the titration process, iodine is added which reacts with water to be reduced to colourless iodide:
[RNH]SO3CH3 + H2O + I2 + 2 RN → [RNH]SO4CH3 + 2 [RNH]I
This reaction continues until there is no water left. The end point is determined by a change in colour due to a surplus of iodine and measured using a potentiometer.
