It is often confused with potassium bitartrate, also known as cream of tartar. Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C 4 H 5 O 6, is a byproduct of winemaking.In cooking it is known as cream of tartar.It is processed from the potassium acid salt of tartaric acid (a carboxylic acid).The resulting powdery acid can be used in baking or as a cleaning solution (when mixed with an acidic solution such as lemon juice or white vinegar). Potassium hydrogen phthalate ("KHP") has the molecular formula "C"_8"H"_5"KO"_4 and is known to be a weak acid. As shown in figure 3 the first acid~base reaction of the tartaric acid is absent.

Stars This entity has been manually annotated by the ChEBI Team. 4.) PART A -- PREPARATION OF 0.1 N SODIUM HYDROXIDE 1. The procedure based on precipitation as potassium hydrogen tartrate was utilised to confirm the concentration of the tartaric acid. It is the potassium salt of tartaric acid. EC number: 212-769-1 | CAS number: 868-14-4 . Molecular Weight 204.22 . Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of tartaric acid first prepared (in about 1675) by an apothecary, Pierre Seignette, of La Rochelle, France.Potassium sodium tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity. 4.) When placed in water, "KHP" dissociates completely into the potassium cation "K"^(+) and the hydrogen phthalate anion, "HP^(-). potassium dihydrogen phosphate: ChEBI ID CHEBI:63036: Definition A potassium salt in which dihydrogen phosphate(1−) is the counterion. The least soluble salt is calcium tartromalate, then calcium tartrate, followed by potassium hydrogen tartrate (KHT), otherwise known as potassium bitartrate or cream of tartar. (See Appendix 6.) Linear Formula HOOCC 6 H 4 COOK . Application Sodium hydrogentartrate may also be used in the preparation of sodium citrate-sodium tartrate reagent, which can complex with interfering metals during the colorimetric estimation of ammonium ions in soil samples. Compare the experimental pKa value for each unknown with the literature values reported in question three. After the dissociation takes place, "HP"^(-) reacts with water to give the hydronium cation, "H"_3^(+)"O", and the phthalate anion, "P"^(2-). 2. sodium carboxyformate hydrate. Hence, the claim of growth of copper doped potassium hydrogen tartrate viz. Submitter Vincent J Fazio Beilstein/REAXYS Number 3637128 . 23. -Potassium hydrogen phthalate –log (3.9x10-6) pKa = 5.41-Potassium hydrogen tartrate –log (4.6x10-5) pKa = 4.34-Acetylsalicylic acid –log (3.2x10-4) pKa = 3.49 4.) It is manufactured from potassium hydrogen tartrate (wine tartar, cream of tartar – a by-product of the wine-making industry) via the calcium salt.
