HChem Double Replacement Reactions

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What does it mean for a compound to be soluble?

Back

A soluble compound is one that can dissolve in a solvent, typically water, to form a solution.

Front

What does it mean for a compound to be insoluble?

Back

An insoluble compound does not dissolve significantly in a solvent, resulting in a solid precipitate.

Front

What is the state of matter symbol for a soluble compound?

Back

(aq), which stands for aqueous, indicating that the compound is dissolved in water.

Front

What is the state of matter symbol for an insoluble compound?

Back

(s), which stands for solid, indicating that the compound does not dissolve in water.

Front

What are the products of the reaction CuCl2 + H2S?

Back

CuS(s) + HCl(aq), where CuS is a solid precipitate and HCl is in aqueous solution.

Front

What is the role of the solubility rules in predicting double replacement reactions?

Back

Solubility rules help determine whether a precipitate will form in a double replacement reaction by indicating which compounds are soluble or insoluble.

Front

What is a precipitate in the context of double replacement reactions?

Back

A precipitate is a solid that forms and separates from a liquid solution during a chemical reaction.

Front

How can you identify a double replacement reaction?

Back

Look for the exchange of ions between two compounds, typically resulting in the formation of a precipitate, gas, or water.
