Predicting Products - Double Replacement & Insolubility

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 are the general products of a double replacement reaction?

Back

The general products are usually two new ionic compounds, one of which may be a precipitate, gas, or water.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, typically water, to form a solution.

Front

What is an insoluble compound?

Back

An insoluble compound is a substance that does not dissolve significantly in a solvent, resulting in a precipitate.

Front

How can you predict the products of a double replacement reaction?

Back

To predict the products, swap the cations and anions of the reactants and check for solubility rules to identify any precipitates.

Front

What is a precipitate?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What are the solubility rules?

Back

Solubility rules are guidelines that help predict whether a compound will dissolve in water or form a precipitate.

Front

Which ions typically form soluble compounds?

Back

Nitrate (NO3-), ammonium (NH4+), and alkali metal ions (Li+, Na+, K+, etc.) typically form soluble compounds.

Front

Which ions typically form insoluble compounds?

Back

Most metal hydroxides (except alkali metals and Ba2+) and carbonates (CO3 2-) are typically insoluble.

Front

What is the net ionic equation?

Back

The net ionic equation shows only the ions and molecules directly involved in the reaction, omitting spectator ions.
