It critiques the inappropriate use of NH3 in precipitating AgCl due to its solubility-increasing effect. Key analytical errors often stem from overlooking chemical interferences. Ladder diagrams are introduced as tools for visualizing equilibrium chemistry, aiding in understanding reaction dynamics and evaluating changes in solution conditions.

The pH of a buffer can be calculated using an ICE table or the Henderson-Hasselbalch approximation. The accuracy of these calculations relies on the pK??? and concentrations being sufficiently large to maintain equilibrium conditions close to their initial values.
