Answer:
Explanation:
C₆H₅NH₂ + H₂O = C₆H₅NH₃⁺ + OH⁻
C₆H₅NH₃⁺ is also called anilinium ion . Thus we see that aniline reacts with water to form anilinium ion and forms OH⁻ ion . Due to it, it shows basic properties . The pH value of this aqueous solution is more than 7 . But it is a weak base because the concentration of OH⁻ formed is very less . It is so due to its less value of Kb . It has been explained as follows
Kb = [tex]\frac{[C_6H_5NH_3^+][OH^-]}{[C_6H_5NH_2][H_2O]}[/tex]
Since Kb is 4.3 x 10⁻¹⁰ which is very low value so concentration of OH⁻ that is [OH⁻] formed will also be very low . Hence it will be a weak base.
