What is sodium tartrate dihydrate?
Sodium tartrate dihydrate is the volumetric standard for Karl Fischer titration. Under normal conditions, it is stable and non-hygroscopic. Sodium tartrate dihydrate has a stoichiometric water content of 15.66% and is primarily used for titer determination in volumetry.
Why we use sodium tartrate in Karl Fischer?
Why we use sodium tartrate in Karl Fischer? The volumetric standard for Karl Fischer titration is sodium tartrate dihydrate. It is stable and non-hygroscopic, under normal conditions. Sodium tartrate dihydrate has a 15.66 percent stoichiometric water content and is primarily used in volumetry to measure the titer.
What is Na2C4H4O6?
Sodium tartrate (Na2C4H4O6) 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.
Is sodium tartrate hazardous?
Ingestion: May cause irritation of the digestive tract. May be harmful if swallowed. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.

What is the taste of sodium tartrate?
It is slightly soluble in alcohol but more completely soluble in water. It has a specific gravity of about 1.79, a melting point of approximately 75 °C, and has a saline, cooling taste.
What is drift in Karl Fischer titration?
Simply put, drift is background moisture that the Karl Fisher titrator is detecting. Well, it is moisture that the Karl Fisher titrator (specifically the detector electrode) is detecting inside the vessel -that’s not coming from your sample.
What is sodium tartrate salt?
Sodium L-tartrate is the organic sodium salt that is the disodium salt of L-tartaric acid. It has a role as a food emulsifier. Sodium tartrate is a disodium salt of l-( + )-tartaric acid that is identified by transparent, colorless, and odorless crystals. It is obtained as a byproduct of wine manufacturing.
What is the pH of sodium tartrate?
