Sulfuric acid is used in titration of oxalate ion as it reacts with oxalate ion to form a white precipitate of calcium oxalate, which makes it easier to detect the end point of the titration. The strong acidity of sulfuric acid also helps in preventing the hydrolysis of the calcium oxalate precipitate.

How do you determine the end point of titration involving sodium oxalate and potassium permanganate?
The end point of the titration is typically determined by observing a color change. In the case of sodium oxalate and potassium permanganate, the permanganate ion is a deep purple color, and it will turn colorless once it has reacted completely with the oxalate ion. This color change indicates the end point of the titration.
What can be the viva questions on oxalate ions?
Oxalates are salts of oxalic acid containing oxalate ion. Oxalate ion is a dianion. Upon protonation, oxalate ion forms a commonly known compound, oxalic acid. The commonly known oxalate salts are sodium oxalate, potassium oxalate etc. The calcium metal ion reacts with oxalate ion to form an insoluble precipitate of calcium oxalate, which is the primary constituent of most of the common kind of Kidney stones.
Is the sulfate ion the conjugate base of sulphuric acid?
Yes, the sulfate ion (SO4^2-) is the conjugate base of sulfuric acid (H2SO4). When sulfuric acid donates a proton (H+), it forms the sulfate ion.
What are the method of titration?
The methods of titration include acid-base titration, redox titration, and complexometric titration. Acid-base titration involves the reaction between an acid and a base to determine the concentration of one of the reactants. Redox titration involves oxidation-reduction reactions to determine the concentration of a substance. Complexometric titration involves the formation of a complex between a metal ion and a complexing agent to determine the concentration of the metal ion.
Is there a different between potassium oxalate and potassium acid oxalate?
Yes, there is a difference between potassium oxalate and potassium acid oxalate. Potassium oxalate is the neutral salt of oxalic acid, while potassium acid oxalate is the acidic form of the salt that contains an additional hydrogen ion. This difference affects their chemical properties and reactions.

What ion is C2O42?
The ion C2O42- is called oxalate ion. It consists of two carbon atoms and four oxygen atoms, with an overall charge of -2. It is commonly found in salts such as potassium oxalate and calcium oxalate.
What is oxalate in chemistry?
Oxalate is a salt or ester of oxalic acid. In chemistry, oxalate typically refers to the oxalate ion, which has a chemical formula of C2O4^2-. Oxalate ions can form complexes with metal ions and are commonly found in foods like spinach and rhubarb.
SO42- acid or base?
It contains the hydroxide ion, making it a base.
Is sulphuric acid an acid or alkali?
Sulphuric acid is an acid because it can donate a hydrogen ion (H+) in a solution, leading to the formation of hydronium ions (H3O+). It is a strong acid that dissociates completely in water to produce hydrogen ions.
Chemical formula for sulphuric?
It refers to SVI ion
What is the formula of ammonium and oxalate ion?
The formula for ammonium ion is NH4+ and the formula for oxalate ion is C2O4^2-.
What is symbol of oxalate?
The symbol for oxalate ion is C2O4^2-.
