Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula HO−C(=O)−C(=O)−OH, also written as (COOH) 2 or (CO 2 H) 2 or H 2 C 2 O 4. It is the simplest dicarboxylic acid .
Sodium oxalate, or disodium oxalate, is a chemical compound with the chemical formula Na 2 C 2 O 4. It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2]
Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).
Calcium oxalate (in archaic terminology, oxalate of lime) is a calcium salt of oxalic acid with the chemical formula CaC 2 O 4 or Ca(COO) 2. It forms hydrates CaC 2 O 4 ·nH 2 O, where n varies from 1 to 3. Anhydrous and all hydrated forms are colorless or white.
Ammonium oxalate is a chemical compound with the chemical formula [N H 4] 2 C 2 O 4.Its formula is often written as (NH 4) 2 C 2 O 4 or (COONH 4) 2.It is an ammonium salt of oxalic acid.It consists of ammonium cations ([NH 4] +) and oxalate anions (C 2 O 2− 4).
In addition to the neutral rubidium oxalate Rb 2 C 2 O 4, there is also an acidic salt, rubidium hydrogen oxalate with the formula RbHC 2 O 4, which is isomorphic to potassium hydrogen oxalate KHC 2 O 4 [10] and forms monoclinic crystals, [11] and an acidic dioxalate with the formula RbHC 2 O 4 ·H 2 C 2 O 4, which exists as a dihydrate, has a ...
A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...
Sodium hydrogenoxalate or sodium hydrogen oxalate is a chemical compound with the chemical formula NaHC 2 O 4.It is an ionic compound.It is a sodium salt of oxalic acid H 2 C 2 O 4.It is an acidic salt, because it consists of sodium cations Na + and hydrogen oxalate anions HC 2 O − 4 or HO−C(=O)−CO − 2, in which only one acidic hydrogen atom in oxalic acid is replaced by sodium atom.
