Picric acid is 2,4,6-trinitro phenol, the nitro groups are electrons withdrawing groups so are responsible to make the bond weaker between oxygen and hydrogen atoms and increase the acidic strength as compare to phenol.

Picric acid is more acidic than phenol because it has three nitro groups (-NO2) which are highly electron-withdrawing and stabilize the negative charge on the conjugate base more effectively. This makes it easier for picric acid to donate a proton, resulting in a stronger acid compared to phenol which has only one -OH group.

for acids in this case, it is because picric acid produces more Hydrogen+ ions in solution than phenol, per same number (moles) of molecules.

Which is more acidic hydrochloric acid or picric acid?
Hydrochloric acid is more acidic than picric acid. Hydrochloric acid fully dissociates in solution to release hydrogen ions, resulting in a lower pH compared to picric acid, which is a weaker acid that does not fully dissociate in solution.
Why is picric acid is called a acid?
Picric acid is called an acid because it contains acidic functional groups that can release hydrogen ions (H+) in solution. These groups include phenol (−OH) groups that can donate protons to water, making it acidic.
Is 1-hexanol more acidic or less acidic than phenol?
Phenol is more acidic than 1-hexanol because the hydroxyl group in phenol is directly attached to the aromatic ring, which stabilizes the resulting phenoxide ion through resonance. In contrast, the hydroxyl group in 1-hexanol is attached to an aliphatic chain, making it less acidic.
Is water more acidic than phenol?
No, water is neutral with a pH of 7. Phenol is slightly acidic with a pH range between 5 and 6.
Why is acetic acid more acidic than phenol?
The two resonating structure of the anion formed after acetic acid gives up a proton are equivalent, and the negative charge rests on oxygen which is an electronegative element. But in case of phenoxide ion, the resonating structures are not equivalent, and negative charge rests on carbon which is an electropositive atom.
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

Is c6h5oh acidic or basic?
C6H5OH is considered acidic. It is more commonly known as phenol, or carbolic acid, which is a type of organic solid known for its volatility and crystalline structure.
Which is more acidic phenol or para-chloro phenol?
Phenol. Anisole doesn't have any acidic protons.
Why is acetic acid more acidic than phenol?
The two resonating structure of the anion formed after acetic acid gives up a proton are equivalent, and the negative charge rests on oxygen which is an electronegative element. But in case of phenoxide ion, the resonating structures are not equivalent, and negative charge rests on carbon which is an electropositive atom.
Why are phenols acidic in nature?
Phenol can act as an acid due to it's stability as phenoxide ion. By releasing H+ ion it will form stable C6H5O- ion. The groups having +I, -I , +M , -M efffects present on phenol will effect acidic nature of phenol. As +I or +M groups which are present at ortho and at para psitions will decrease the acidic character of phenol. If they are at meta position effect is less than at para or ortho positions.Similar to this -I or -M gorups are substituted on phenol they will increase the acidic nature. so, we can say that as the stability of phenoxide ion increases acidic nature of phenol also increases.Phenol can act as an acid due to it's stability as phenoxide ion.

Is alcohol acidic or basic?
Alcohol is neutral in pH. It is neither acidic nor basic.
Why phenol is more acidic than ethanol?
phenol is more acidic because of the benzene ring present in the molecule,when you lose the H form the OH group it is possible to delocalise the charge around the aromatic system due to the pi electron cloud,straight chain alcohols cannot do this so it is less favourable to deprotonate them hance it is easier to deprotonate a phenol,hence we say it is more acidic
Which is a stronger acid cresol or phenol?
Cresol is a stronger acid than phenol because it has an additional methyl group that stabilizes the negative charge after donating a proton. This makes it easier for cresol to lose a proton compared to phenol.
