2024/2025 Net Ionic Equations Review Flashcardizz

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the chemical reaction and remain unchanged in the solution. They are present in the reactants and products but do not affect the overall reaction.

Front

What does the abbreviation (s) indicate in a chemical equation?

Back

The abbreviation (s) indicates that the substance is a solid, often used to denote a precipitate formed in a chemical reaction.

Front

Which reaction produces a precipitate?

Back

The reaction between AgNO3(aq) and NaOH(aq) produces a precipitate of AgOH(s).

Front

What is a net ionic equation?

Back

A net ionic equation shows only the species that participate in a chemical reaction, omitting the spectator ions.

Front

How do you identify spectator ions in a reaction?

Back

To identify spectator ions, write the complete ionic equation and then remove the ions that appear unchanged on both sides of the equation.

Front

What is the net ionic equation for the reaction of Ba(MnO4)2(aq) and (NH4)2SO4(aq)?

Back

The net ionic equation is Ba^2+(aq) + SO4^2-(aq) → BaSO4(s).

Front

What is the net ionic equation for the reaction between K3PO4(aq) and CuSO4(aq)?

Back

The net ionic equation is 2 Cu^2+(aq) + 3 PO4^3-(aq) → Cu3(PO4)2(s).

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two aqueous solutions react.

Front

What is the role of a precipitate in a chemical reaction?

Back

The formation of a precipitate indicates that a chemical reaction has occurred, often signaling the formation of a new compound.

Front

What does the abbreviation (aq) mean in a chemical equation?

Back

The abbreviation (aq) means that the substance is dissolved in water, indicating an aqueous solution.
