3.3: Single and Double Displacement Reactions

Flashcards covering chemical reactions and related concepts.

Single Displacement Reactions

Occurs when one element replaces another element in a compound

A + BC → AC + B

Metals replace metals and non-metals replace non-metals

Using the Activity Series

Metals higher on the activity series can displace metals lower on the activity series

No Reactions

Reaction will not occur if you try to displace a metal that is higher on the activity series

Halogen Activity Series

Lists halogens in order of activity

Double Displacement Reactions

Reaction between 2 soluble ionic compounds where cation from one species changes places with cation from other species

Double Displacement Reactions

Each compound must be in an aqueous form so that the ions can dissociate from each other and switch partners

Solubility

Used to check the solubility of the new compounds to determine if they are soluble (aq) or a precipitate (s)

Neutralization Reactions

Water is formed when an acid and a base are combined

H2SO4 (aq) + Ca(OH)2 (aq) → CaSO4 (s) + 2 H2O (l)

Sulfuric acid reacting with calcium hydroxide to form calcium sulfate and water
