Net Ionic Equations

Front

What is a net ionic equation?

Back

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

How do you identify spectator ions in a reaction?

Back

Spectator ions are ions that do not change during the reaction and are present in the same form on both sides of the equation.

Front

What is the first step in writing a net ionic equation?

Back

The first step is to write the balanced molecular equation for the reaction.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides.

What does (aq) signify in a chemical equation?

Back

(aq) indicates that a substance is dissolved in water, meaning it is in an aqueous solution.

Front

What does (s) signify in a chemical equation?

Back

(s) indicates that a substance is in solid form, often referring to a precipitate formed in a reaction.
