Precipitation Reactions

Front

What is a precipitation reaction?

Back

A chemical reaction in which two solutions react to form an insoluble solid, known as a precipitate.

Front

What is a precipitate?

Back

A solid that forms and settles out of a liquid mixture during a precipitation reaction.

Front

What are spectator ions?

Back

Ions that do not participate in the actual precipitation reaction and remain unchanged in the solution.

Front

What is a net ionic equation?

Back

An equation that shows only the ions and molecules directly involved in a precipitation reaction, excluding spectator ions.

Front

What is the role of water in precipitation reactions?

Back

Water acts as a solvent that dissolves ionic compounds, allowing them to react and form precipitates.

Front

What are cations?

Back

Positively charged ions that are attracted to the cathode in electrolysis.

Front

What are anions?

Back

Negatively charged ions that are attracted to the anode in electrolysis.

Front

How do you identify a precipitate in a reaction?

Back

A precipitate can be identified by observing the formation of a solid that separates from the liquid.

Front

What is the significance of solubility rules in precipitation reactions?

Back

Solubility rules help predict whether a precipitate will form when two ionic solutions are mixed.

Front

What happens when two soluble salts are mixed?

Back

They may react to form an insoluble salt, resulting in a precipitation reaction.
