Write ionization equations and base ionization constant expressions for the following based. a. butylamine

Butylamine is a weak base, and it can ionize in water to form the butylammonium ion (C4H9NH3+) and hydroxide ion (OH-).

Ionization equation:
C4H9NH2 + H2O -> C4H9NH3+ + OH-

Base ionization constant expression (Kb):
Kb = [C4H9NH3+][OH-] / [C4H9NH2]
