Question

Any reaction that produces an insoluble precipitate can be called a:

• A. Redox reaction
• B. Displacement reaction
• C. Precipitation reaction
• D. Decomposition reaction

Answer 1

Answer:

C. Precipitation reaction

A reaction that results in the formation of an insoluble precipitate is termed a precipitation reaction. Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
