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.
Formic acid is more acidic than benzoic acid. This is because formic acid has a simpler molecular structure with a hydrogen atom attached to a carboxyl group, making it easier to release the acidic hydrogen ion compared to benzoic acid, which has a more complex aromatic ring structure.
yes formic acid is stronger than acetic acid.
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.
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.

Acetic acid is stronger than formic acid.
Formic acid is commonly used as an additive in LC-MS mobile phases due to its strong acidity and volatility, which can enhance ionization efficiency. Acetic acid, while also acidic, is less volatile than formic acid and may produce less intense signals in mass spectrometry. Choosing between the two would depend on the specific requirements of the analysis and instrument sensitivity.
Nitric acid is stronger than formic acid. Nitric acid is a strong acid with a lower pKa value, meaning it is a better proton donor compared to formic acid. This makes nitric acid more corrosive and reactive than formic acid.
Hydrochloric acid would be more acidic than honeybee venom. Honeybee venom typically has a pH of around 5.0, while hydrochloric acid has a much lower pH, usually between 0 and 1. This means that hydrochloric acid is a stronger acid and more corrosive than honeybee venom.
As we know that acetic acid is CH3 substituted formic acid .since CH3 is an electron donating relative to hydrogen .so, it donates the electron to carboxyl group and makes it more negative. this phenomenon makes acetic acid weaker acid than formic acid .Thus formic acid is stronger acid than acetic acid.
