What happens when oxalic acid reacts with concentrated Sulphuric acid?

The concentrated sulphuric acid removes water from oxalic acid. So, heating of oxalic acid in presence of concentrated sulphuric acid produces carbon monoxide gas, carbon dioxide gas, and a water molecule.

Why oxalic acid is used in titration of NaOH?

Theory. Since sodium hydroxide is not a primary standard a standard solution of oxalic acid is prepared and used for standardisation of sodium hydroxide. In acid base titration at the end point the amount of acid becomes chemically equivalent to the amount of base present.

Which indicator is used in the titration of oxalic acid vs sodium hydroxide can the titration be performed by using some other indicator?

phenolphthalein
Hence, the indicator used for the titration of oxalic acid with sodium hydroxide is phenolphthalein.

Why concentrated H2SO4 is used in titration?

Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction.

When oxalic acid reacts with conc H2SO4 two gases produced are neutral?

H2SO4, two gases produced are of neutral and acidic in nature respectively. Potassium hydroxide absorbs one of the two gases.

What is the best method for determining the concentration of a NaOH solution?

titration
One method for concentration determination of sodium hydroxide solutions is titration, where correct and precise results are neither trivial nor quick. Besides, the operator is exposed to the caustic sample. Another method is the determination of the solution’s density, and, derived therefrom, its concentration.

Why phenolphthalein is suitable indicator for titration of benzoic acid with NaOH?

In a titration of acetic acid with NaOH, phenolphthalein is an ideal indicator because it changes color just at the pH of the equivalence point.

How do you find the strength of NaOH in a titration?

1. Molarity of the given oxalic acid solution = \frac{M}{20} Volume of oxalic acid solution taken for each titration = 20 ml (V1).
2. Molarity of the given oxalic acid solution = \frac{M}{20}
3. The strength of the given sodium hydroxide solution is \frac { 80 }{ x } \quad g { L }^{ -1 }

Why is sulphuric acid added to oxalic acid titration?

Sulfuric acid is used because it is stable towards oxidation; whereas, for example, hydrochloric acid would be oxidized to chlorine by permanganate.

Why is sulphuric acid used in KMnO4 titration?

Titrations with Permanganate must be carried out in strong acid solution. Sulfuric Acid is generally used for this purpose because Nitric Acid and Hydrochloric Acid can participate in competing oxidation-reduction reactions, reducing the accuracy of the titration.
