Questions & Step-by-Step Solutions
What is the primary driving force for the formation of a precipitate in a double displacement reaction?
Step 1: Understand what a double displacement reaction is. This is a type of chemical reaction where two compounds exchange ions or elements to form new compounds.
Step 2: Recognize that in some double displacement reactions, one of the products is a solid that does not dissolve in water. This solid is called a precipitate.
Step 3: Know that the formation of a precipitate is important because it indicates that a reaction has occurred.
Step 4: Realize that the driving force for the reaction is the formation of this solid precipitate, which reduces the number of dissolved ions in the solution.
Step 5: Conclude that the decrease in solubility of the reactants and the formation of a solid product is what drives the double displacement reaction forward.
