Pyrrole C4H4NH (in which N contributes a lone pair) has a pKa - 3.8, but Pyridine (where N is part of the ring's double bond) has a pKa 5.14. Electron pair availability indicates the strength of basicity. In this case, pyridine is the stronger base.
Pyrrole is less basic than pyridine because the lone pair of electrons on the nitrogen in pyrrole is part of the aromatic system and less available for donation compared to the lone pair on the nitrogen in pyridine. This makes pyridine more basic than pyrrole.
Pyrrole is a weak acid due to the presence of a lone pair on the nitrogen atom that can donate a proton. However, it is generally less acidic than alcohols or carboxylic acids. Its conjugate base, the pyrrole anion, is stabilized by aromaticity.
Pyrrole and pyridine are both aromatic compounds, but they differ in their chemical structures and properties. Pyrrole has a five-membered ring with four carbon atoms and one nitrogen atom, while pyridine has a six-membered ring with five carbon atoms and one nitrogen atom. Pyrrole is more reactive due to its higher electron density, while pyridine is less reactive and more stable. Pyrrole is a stronger base than pyridine because its nitrogen atom is more basic. Additionally, pyrrole is more acidic than pyridine because its nitrogen atom can donate a proton more easily.
Pyrrole does not react with hydrochloric acid because the nitrogen atom in the pyrrole ring is part of an aromatic system. The lone pair of electrons on the nitrogen atom is delocalized within the aromatic ring, making it less available for reaction with acids.
Hello, We can approach an answer to this question by doing the resonance forms of both compounds,,, and we can then conclude that the lone pair found in pyrrole ( 5-membered ring ) is involved in the five resonance forms while on the other hand the lone pair found in the pyridine ( 6-membered ring ) is NOT involved in the two resonance forms and this leads to form a concentrated charge in case of pyridine. SO,,, pyrrole has the lone pair totally involved in the resonance and this means that there is not concentrated charge on the (N) which makes pyrrole a weaker bas than the Pyridine. Hope The Answer Was brief and Helpful ALKASED

The pH scale measures how acidic or basic a substance is.A pH less than 7 is acidic, and a pH greater than 7 is basic.hence a level of 5 is acidic.

Litmus paper is a tool to identify the acidic or basic character of a substance and without water the acidic or basic nature is meaning less.

A Ph of 7 is neutral, anything more is acidic, anything less is basic.
Neither is acidic, both are basic. But milk of magnesia is less basic and therefore more acidic.
Acidic liquids tend to rust a paper clip faster than basic liquids. Acidic solutions, such as vinegar or lemon juice, can accelerate the corrosion process by increasing the rate of oxidation of the metal in the paper clip. Basic liquids, on the other hand, are less corrosive and are less likely to cause rusting in a paper clip.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
Basic solutions have a higher concentration of hydroxide ions (OH-) compared to acidic solutions. This property allows basic solutions to have a pH greater than 7, while acidic solutions have a pH less than 7.
