Aniline, benzenamine, abbreviated C6H5NH2, is an important organic base used in the manufacture of dyes. In a certain manufacturing process, it is necessary to keep the concentration of CH3NH₂ (aniline's conjugate acid, the anilinium ion) below 1.0 x 10 M in a solution that is 0.10 M in aniline. a. Find the concentration of the anilinium ion in this solution. b. Find the concentration of NaOH required to lower the anilinium ion in the manufacturing process. -NH₂ Kb=4.3 x 10-10

2. Aniline, benzenamine, abbreviated C6H5NH2, is an important organic base used in the
manufacture of dyes. In a certain manufacturing process, it is necessary to keep the
concentration of C6H5NH3* (aniline's conjugate acid, the anilinium ion) below
1.0 x 10-9 M in a solution that is 0.10 M in aniline.
a. Find the concentration of the anilinium ion in this solution.
b. Find the concentration of NaOH required to lower the anilinium ion in the
manufacturing process.
