Double displacement reactions usually occur in:
-
A.
aqueous solution
-
B.
gaseous state
-
C.
all three states
-
D.
solid state
Correct Answer:
A. aqueous solution
Explanation:
The correct answer is Option A: aqueous solution.
Double displacement reactions, also known as metathesis reactions, primarily take place when two ionic compounds are dissolved in water. In an aqueous environment, these compounds dissociate into their respective cations and anions, allowing the ions to move freely and exchange partners. This process leads to the formation of new products, such as a solid precipitate, a gas, or a molecular compound like water. While some displacement reactions can occur in other states, the standard double displacement reactions studied in chemistry are defined by this exchange of ions in a liquid solution.
