Why is methanoic acid more acidic than benzoic acid?
We would certainly expect benzoic acid to be more acidic than methanoic acid, due to stabilisation of the benzoate anion caused by the delocalisation of the electrons on the oxygen atom over the benzene ring. However, in practice, it is found that methanoic acid is actually more acidic than benzoic acid(has a greater Ka value). This is because methanoic acid is more soluble in water than benzoic acid, so there is greater ionisation of methanoic acid in water than benzoic acid.
Which is more acidic benzoic acid or acetic acid?
Benzoic acid is the stronger acid compared to ethanoic acid. However, ethanoic acid is more corrosive and will burn skin etc more than benzoic acid. Corrosivity/burn potential are not the same as acid strength. This is due to the delocalisation of the lone pair of electrons on the oxygen atom into the benzene, increasing the polarity of the -OH bond and thus makes the cleaving of the H+ ion easier. The delocalisation of electrons into the benzene ring also stabilises the carboxylate ion. Therefore the position of equilibrium lies more to the right and this shows that benzoic is a more acidic acid. The simplified version is that a benzene ring is electron withdrawing and a methyl group is electron releasing. The electron withdrawing power makes the releasing of the H+ ion easier.
Formic acid is stonger than acetic acid?
yes formic acid is stronger than acetic acid.
What is more acidic acetic acid or formic acid or prop ionic acid?
Formic acid is more acidic because formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.
Which is more acidic ortho-nitro benzoic acid or ortho-methoxy benzoic acid?
Ortho-nitrobenzoic acid is more acidic than ortho-methoxybenzoic acid because the nitro group is an electron-withdrawing group that stabilizes the negative charge on the conjugate base through resonance, making it easier to lose a proton. The methoxy group, on the other hand, is an electron-donating group that destabilizes the conjugate base, making it less acidic.

What is the picricacid formual?
picric acid (or 2,4,6-trinitrophenol) is more acidic than benzoic acid The pKa or picric acid is 0.3 and that of benzoic acid is 4.2

What should be the approximate pH and composition of aqueous system to dissolve benzoic acid?
To dissolve benzoic acid, the aqueous system should be slightly acidic with a pH around 2-3. This can be achieved by adding a small amount of hydrochloric acid to water. Benzoic acid is sparingly soluble in pure water but dissolves more readily in an acidic solution due to the formation of benzoate ions.
Which is more acidic benzoic acid or o-acetylbenzoic acid?
They have about the same strength. However, 2-acetylbenzoic acid should be slightly more acidic due to electron push from the oxygen atoms (and we are talking only SLIGHTLY). o-acetyl groups can be used to direct reactions to a particular position on the benzoic ring...depending on which reaction, and which position you are trying to diversify... I believe...

How much more acidics is Formic acid than methylamine?
Formic acid is more acidic than methylamine because it can donate a proton more readily due to the presence of the carboxylic acid group, while methylamine has a weaker basicity and is less likely to donate a proton. This results in formic acid having a lower pKa value compared to methylamine, indicating higher acidity.
Is acetic acid or formic acid is more stronger?
Formic acid is about ten times stronger.
Why formic acid is more acidic than acetic acid?
Because it has a greater/higher Ka (dissociation constant). This is related to the ease with which the H+ can be released from the COOH group.
