Homework Statement
An example of a precipitation reaction: Aqueous silver nitrate (AgNO3) is added to a solution containing potassium chloride (KCl) and the precipitation of a white solid, silver chloride is observed. (Zumdahl, 2005)
The silver chloride (AgCl) has formed a solid, which is observed as a precipitate.
This reaction can be written emphasizing the dissociated ions in a combined solution. This is known as the ionic equation.
Ag+ (aq) + NO3− (aq) + K+ (aq) + Cl− (aq) → AgCl (s) + K+ (aq) + NO3− (aq)
Homework Equations
none.
The Attempt at a Solution
Okay, so I know that the AgCl(s) precipitate forms but how come the K+ and the NO3- do not combine to form KNO3(s)? And how would I know that KNO3(s) is not the formed precipitate?
