Chemical compound
Sodium tartrate (Na2 C4 H4 O6 ) is a salt used as an emulsifier and a binding agent in food products such as jellies , margarine , and sausage casings. As a food additive , it is known by the E number E335.
It is made by the combination reaction of baking soda /Sodium Bicarbonate (NaHCO₃) with tartaric acid .
Because its crystal structure captures a very precise amount of water , it is also a common primary standard for Karl Fischer titration , a common technique to assay water content.
