ADissolved substances react to form a solid product
BDissolved substances react to form a gaseous product
CA hydrogen ion moves from one species to another
DElectrons move from one reactant to another one
Answer & Solution
Correct answer: A. Dissolved substances react to form a solid product
1. In a precipitation reaction the reactants are dissolved in solution.
2. They react to form one or more products that are solids.
3. That insoluble solid is the precipitate.
4. Transfer of hydrogen ions defines an acid-base reaction, and transfer of electrons defines a redox reaction.
