How do you determine the pka of oxalic acid?
The pka of oxalic acid can be determined with the help of titration curve. The slight inflection that occurs corresponds to the first end point.
Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
Can oxalic acid be used for standardization of strong base?
Yes, in fact it is the only acknowledged acid (DIN, ASAC, NEN) to be used with standardisation in analytical titration chemistry (volumetrics > > titrimetrics > acidimetry). By the way, it is also used in oxidimetric standardisation.
How is oxalic acid extracted from guava fruit?
A mash of guava fruit is oxidized in the presence of vanadium pentoxide. This produces the diesters of oxalic acid which are then hydrolyzed to oxalic acid.
What are oxalic acid?
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
Why oxalic acid is acidified before titration?
for medium produce
What is oxalic acid used for?
It is a weak acid mainly used for TITRATION
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
How do you determine the pka of oxalic acid?
The pka of oxalic acid can be determined with the help of titration curve. The slight inflection that occurs corresponds to the first end point.
Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.
Balanced equation for oxalic acid and potassium permanganate?
2co +o2 ---> 2co2
Why heat oxalic acid before titrate with potassium permanganate?
The oxalic acid is heated to icrease the rate of reaction which is very slow at room temperature
Is there a different between potassium oxalate and potassium acid oxalate?
sorrel salt: potassium hydrogen oxalate or potassium hydrogen oxalate, KHC2O4 (sal acetosella, salt of lemon). Here only one 'H' is replaced with 'K' in oxalic acid to get HOOC-COOK. Potassium oxalate is KOOC-COOK.
Which indicator is used in titration of oxalic acid with HCl?
Both HCl and oxalic acid are acids. Therefore, since there is no alkali present, these compounds do not undergo neutralization. So there is no suitable indicators for the addition of these two reagents.
