Flashcards

Single Displacement Reaction

A chemical reaction where one element replaces another in a compound.

Metal Replacement in Single Displacement

In a single displacement reaction, the metal involved will always replace the positive ion in the compound.

Non-metal Replacement in Single Displacement

In single displacement, a non-metal like chlorine can replace another non-metal in a compound.

Double Displacement Reaction

A chemical reaction where two elements in different compounds swap places.

Study Notes

Single Displacement Reactions

In a single displacement reaction, one element replaces another element in a compound.
If the reacting element is a metal, it replaces the metal in the compound.
If the reacting element is a non-metal, it replaces the non-metal in the compound.
In reactions involving an ionic compound and a metal, the positive ion (cation) is replaced.
Example: CaI₂ + Cl₂ → CaCl₂ + I₂
Often occur in aqueous solution. Polyatomic ions remain unchanged.
Can occur when metals are placed in acid. Hydrogen acts like a metal in these reactions.
General pattern: A + BC → AC + B

Double Displacement Reactions

In double displacement reactions, elements in different compounds swap places.
Metal replaces metal, and non-metal replaces non-metal.
Metals can also displace hydrogen.
Often occur between two ionic compounds in solution.
Some ionic compounds are insoluble in water.
- If an insoluble compound forms, it appears as a precipitate, a solid in a liquid.
Not all double displacement reactions result in precipitation.
General pattern: AB + CD → AD + CB
