The reaction of the weak base aniline, C6H5NH2, with the strong acid What is a conjugate base and a conjugate acid? Aniline can alternatively be prepared from ammonia and phenol derived from the cumene process. Write two balanced chemical equations to illustrate this property.
Strong acid. Justify your answers. Substituting the expressions for the equilibrium concentrations into the equation for the ionization constant yields: \(=\dfrac{(x)(x)}{0.10x}=1.4 \times 10^{5}\), \[\ce{[H3O+]}=0+x=1.210^{3}\:M \nonumber \], \[\mathrm{pH=log[H_3O^+]=2.92(an\: acidic\: solution)} \nonumber \]. 3.2 * 10 9. {C6H5NH3+}\) is the stronger acid (a) (b) .

Without the harmful bacteria consuming the cucumbers they are able to last much longer than if they were unprotected. THANKS! [24][25] In 1842, Nikolay Nikolaevich Zinin reduced nitrobenzene and obtained a base that he named benzidam. We frequently see the formula of this ion simply as Al3+(aq), without explicitly noting the six water molecules that are the closest ones to the aluminum ion and just describing the ion as being solvated in water (hydrated).
