Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Activity Series
The activity series is a list of metals ranked by their ability to displace other metals from compounds in solution. Metals higher in the series can displace those lower from their compounds, which is crucial for predicting whether a reaction will occur when two metal solutions are mixed.

Activity Series Chart
Double Displacement Reaction
A double displacement reaction occurs when two compounds exchange ions to form two new compounds. This type of reaction is common in aqueous solutions and can be represented by the general formula AB + CD → AD + CB, where A and C are cations and B and D are anions.

Solubility Rules
Solubility rules help predict whether a compound will dissolve in water. For example, most nitrates are soluble, while many sulfates are not. Understanding these rules is essential for determining if a precipitate will form during a reaction, which influences the overall reaction outcome.
