Problem
An aqueous buffer is prepared from 0.30 M NH3 and 0.30 M NH4Cl. A student adds a small pellet of solid NaOH that dissolves completely in the buffer without significantly changing its volume.
(a) Write the balanced molecular equation that represents the reaction of the base with the appropriate component of the buffer.
(b) Convert the equation written in part (a) to its net ionic form, clearly indicating physical states.
(c) Explain why chloride ions are considered spectator ions in this system.
