How can you separate diethyl tartrate once you have produced it using tartaric acid and ethanol in esterification?

I am assuming that by separation, you are asking it to purify diethyl tartrate. This can be done with chromatography, since polarity ranks in diethyl tartrate > ethanol > tartaric acid. This could also be done with distillation under vacuum, and thus these molecules can be isolated.
If the question is asking to do the reverse reaction, as in to hydrolyze diethyl tartrate, you can add a base to break this compound into two molecules: the salt form of tartarate and ethanol.

Is sodium potassium tartrate ionic or covalent?
Sodium potassium tartrate is ionic. Tartaric acid is covalent.
Why is tartaric acid named for tartarus?
It is not. There is no connection between tartar, the ancient name for Potassium Tartrate (after which Tartaric Acid is named) and Tartarus, the ancient name for Hell.
How you prepare Sodium Tartrate Buffer pH-5?
10 mM tartaric acid (sodium) buffer solution (pH=4.2) Tartaric acid (M.W.=150.09)..........................2.5 mmol (0.375 g) Sodium tart rate dihydrate (M.W.=230.08)........7.5 mmol (1.726 g) Add water to make up to 1 L. 10 mM tartaric acid (sodium) buffer solution (pH=2.9) Tartaric acid (M.W.=150.09)..........................7.5 mmol (1.13 g) Sodium tartrate dihydrate (M.W.=230.08)........2.5 mmol (0.58 g) Add water to make up to 1 L.
What is tartaric acid at room temperature?
Tartaric acid is a white crystalline diprotic organic acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of tartaric acid are known as tartrates. It is a dihydroxy derivative of succinic acid.Tartaric acid was first isolated from potassium tartrate, known to the ancients as tartar, c. 800 by the Islamic alchemist Jabir ibn Hayyan.[3]The modern process was developed in 1769 by the Swedish chemist Carl Wilhelm Scheele. The chirality of tartaric acid was discovered in 1832 by Jean Baptiste Biot, who observed its ability to rotate polarized light. Louis Pasteur continued this research in 1847 by investigating the shapes of ammonium sodium tartrate crystals, which he found to be asymmetric. Pasteur was the first to produce a pure sample of levotartaric acid.

Is sodium potassium tartrate ionic or covalent?
Sodium potassium tartrate is ionic. Tartaric acid is covalent.
What is a bitartrate?
A bitartrate is another name for a hydrogen tartrate - a univalent salt of tartaric acid.
Why is tartaric acid named for tartarus?
It is not. There is no connection between tartar, the ancient name for Potassium Tartrate (after which Tartaric Acid is named) and Tartarus, the ancient name for Hell.
What is the chemical composition of tartrate?
Tartaric acid: HOOC-CHOH-CHOH-COOH ( = C4H6O6)Named: 2,3-dihydroxi-butanedioic acid)The salts of this acid are called 'tartrate' salts.A mixture of this acid or salts with baking powder is called 'cream of tartar' (but I don't know why)
How do you prepare 25mM sodium tartrate buffer pH 2.5?
Tartaric acid - 18.75 mM Sodium Tartrate Dihydrate - 6.25 mM pH of this mixture should be near 2.9, adjust pH down to 2.5 using HCl, and QS to 1 L by water.

What are the scientific names of the chemicals in baking powder?
Baking powder is a mixture of tartaric acid and bicarbonate of soda (sodium hydrogen carbonate). The acid releases gas (carbon dioxide) from the bicarbonate. Depending on the formulation, the tartaric acid may be replaced by cream of tartar (potassium bitartrate, also called potassium hydrogen tartrate).
What does tartrate stand fo after a drug name?
It doesn't "stand for" anything. It means the drug is supplied as the tartrate salt.Many druglike molecules are bases. Converting them into salts helps them dissolve in water better. "Tartrate" means the acid used to produce the salt was tartaric acid, O=C(O)C(O)C(O)C(=O)O (2,3-dihydroxybutanedioic acid).Tartaric acid is technically a toxin, but you'd have to eat a lot of it to kill you: a 70 kg adult would need to eat about a pound to have a fifty-fifty chance of dying, so it's perfectly safe to use in foods or drugs.
Is there any relationship between tartar and tartaricum?
Tartar - Some of the many meanings:Tartar sauceTartar on teeth, hardened dental plaqueSalts of tartaric acidCream of tartar (potassium bitartrate)Tartar emetic (antimony potassium tartrate)Tartrate -noun Chemistry.tar⋅trate /ˈtɑr treɪt/ Show Spelled Pronunciation [tahr-treyt]Origin: 1785-95; tartr- (comb. form repr. tartar ) + -ate 2A tartrate is a salt or ester of the organic compound tartaric acid, a dicarboxylic acid.

Is calcium tartrate an organic or inorganic compound?
Ca-tartrate (2,3-Dihydroxybutanedioic acid calcium salt, CaC4H4O6) is the Ca-salt of a diprotic acid. That is the IN-organic part of the story. The ORganic part is the tartaric acid (2,3-Dihydroxybutanedioic acid, H2C4H4O6) of which it is formed eg. as a product 'defect' in grape wine making proces. Structural formula: (COOH)-CHOH-CHOH-(COOH)
Which gas will be evolved if Sodium bicarbonate is added to a solution of Tartaric acid. How will you test this gas?
You should get carbon dioxide (CO2). Combining sodium bicarbonate to tartaric acid will yield water-soluble sodium tartrate and carbonic acid. Carbonic acid (H2CO3) will instantly decompose into water and carbon dioxide. Collect the gas, pour it over a lit candle flame. The flame will go out, proving that it's CO2. sodium bicarbonate and Tartaric acid together in dry form are baking powder.
