Calculate the concentrations of hydrogen ion and hydroxide ion at 25 degrees C.
1. Aniline, C6H5NH2, is used in the manufacturing of some perfumes. What are the values for a 0.035 M solution?
Kb= 4.2 x 10-10
2. For a solution in which 10.0 mL of 0.100 M HCl is added to 25.0 mL of 0.100 M NaOH

To solve your first question, you have to recognize it is a weak acid/base type problem. Aniline has a Kb value, which means it is a weak base.
For these types of questions, there is a simple formula that you must familiarize yourself with.
Kb = x^2 /C-x ( and the -x in the denominator is almost always assumed to not be ...
This solution answers two general chemistry questions that calculate the concentrations of hydrogen ion and hydroxide ion at 25 degrees C.
