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 ...
If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point. For example, the titration curve for the titration between oxalic acid (a weak acid) and sodium hydroxide (a strong base) is
Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, water-soluble salt with ferric iron, ferrioxalate ion. Oxalic acid is an ingredient in some tooth whitening products.

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]
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.
Oxalyl chloride is an organic chemical compound with the formula Cl−C(=O)−C(=O)−Cl. This colorless, sharp-smelling liquid, the diacyl chloride of oxalic acid, is a useful reagent in organic synthesis. [4]
Tin(II) oxalate is an inorganic compound, a salt of tin and oxalic acid with the chemical formula SnC 2 O 4. [2] The compound looks like colorless crystals, does not dissolve in water, and forms crystalline hydrates.
