Thermometric titration – the better method to determine total sodium in foodstuffs
A commonly used method for quantifying sodium in foodstuffs is to determine the counterion chloride using argentometric titration, the concentration of which can be used to deduce the sodium concentration from the 1:1 stoichiometry of sodium chloride. This method involves errors because sodium is not only present with chloride as the counterion. A new method... Read more
