Problem
An aqueous solution of Pb(NO3)2 is mixed with an aqueous solution of KI. A yellow solid forms immediately while the remaining solution is clear and colorless. Which type of reaction is most consistent with these macroscopic observations?
(a) Acid–base neutralization yielding water
(b) Formation of a colored complex ion in solution
(c) Precipitation reaction producing an insoluble salt
(d) Redox reaction involving electron transfer
