Sodium in dairy products

The sodium content of beverages is usually determined indirectly through a precipitation reaction with silver nitrate. This approach assumes that the chloride ions are present in a molar ratio of 1:1 with the sodium ions, which is not always the case. On the other hand, established methods for the direct...
