The pH of a 0.233m solution of anilinium chloride is 2.64.
What is ph of solution?
A solution's acidity is determined by its hydrogen ion concentration, which is measured by its pH. Pure water slightly splits into hydrogen and hydroxyl (OH) ions with equal proportions.
Aniline hydrochloride is conjugate acid of aniline. For calculation of pH we have to find pKa of C6H5NH2HCl and it behaves as a weak acid.
pKa+pKb= pKw
Kb= 4.6×10⁻¹⁰
pKa=14-(-log4.6ₓ10⁻¹⁰)
=4.66
pH=1/2pKa-1/2logc(c=0.233)
=4.66/2+0.63/2(logc= -0.63)
pH= 2.64

What purposes does aniline hydrochloride serve?
A powdery, crystalline (sand-like) green or white substance is aniline hydrochloride. It is employed in printing, dyeing, and the synthesis of other compounds.
In order to create polyaniline-coated poly(styrene-co-styrene sulfonate) nanoparticles, aniline hydrochloride was utilized. In the rat spleen and in response to aniline exposure, base excision repair (BER) mediated by 8-oxoguanine glycosylase 1 and Nei-like DNA glycosylases (NEIL1/2) was studied. It is a component of paints, paint removers, and clothes marking inks. Additionally, it is utilized as a shoe and stove polisher.
Commercially, aniline is made by either ammonia reacting with chlorobenzene or catalyzing the hydrogenation of nitrobenzene. Iron borings dissolved in aqueous acid are another method for reducing nitrobenzene
