Net Ionic Equations

Front

What is a Net Ionic Equation?

Back

A chemical equation showing only the species which are actively involved in the reaction.

Front

Front

What are the numbers that you CANNOT change in a chemical equation?

Back

Subscripts.

Front

In the equation CuCl2 + NaOH → Cu(OH)2 + NaCl, which product is insoluble?

Back

Front

What is a precipitate?

Back

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

Front

What does it mean for a compound to be soluble?

Back

It means the compound can dissolve in a solvent, typically water.

Front

What is the role of spectator ions in a chemical reaction?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged.

Front

How do you write a net ionic equation?

Back

1. Write the balanced molecular equation. 2. Separate the soluble strong electrolytes into ions. 3. Remove the spectator ions. 4. Write the remaining ions as the net ionic equation.

Front

What is the difference between a molecular equation and a net ionic equation?

Back

A molecular equation shows all reactants and products in their molecular form, while a net ionic equation shows only the ions that participate in the reaction.
