QUESTION 25
± Weak Base Calculations
Many common weak bases are derivatives of NH3, where one or more
of the hydrogen atoms have been replaced by another substituent.
Such reactions can be generically symbolized as
NX3(aq)+H2O(l)⇌HNX3+(aq)+OH−(aq)
where NX3 is the base and HNX3+ is the conjugate acid. The
equilibrium-constant expression for this reaction is
Kb=[HNX3+][OH−][NX3]
where Kb is the base ionization constant. The extent of
ionization, and thus the strength of the base, increases as the
value of Kb increases....

Question 1:For many weak acid or weak base calculations, you can
use a simplifying assumption to avoid solving quadratic
equations.Classify these situations by whether the assumption is
valid or the quadratic formula is required.

Titration of Weak Acid with Strong Base
A titration involves adding a reactant of known quantity to a
solution of another reactant while monitoring the equilibrium
concentrations. This allows one to determine the concentration of
the second reactant. The equation for the reaction of a generic
weak acid HA with a strong base is
HA9(aq)+OH-(aq)
----->
A-(aq)+H2O(l)
A certain weak acid, HA, with a Ka value of
5.61x10-6, is titrated with NaOH
Part A
A solution is made by...
