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.

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged on both sides of the equation.

Front

How do you write a net ionic equation?

Back

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

What is the precipitate formed when lead (II) nitrate reacts with sodium chloride?

Back

Lead (II) chloride (PbCl2) is the precipitate formed.

Front

Which type of reaction typically does not have a net ionic equation?

Back

Reactions that do not involve the formation of a solid, liquid, or gas, such as combustion reactions, typically do not have a net ionic equation.

Front

What is the role of solubility rules in predicting precipitate formation?

Back

Solubility rules help predict whether a compound will dissolve in water or form a precipitate when mixed with another solution.

Front

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

Back

Ba^2+ + SO4^2- → BaSO4 is the net ionic equation.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds.

Front

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

Back

The formation of a precipitate indicates that a chemical reaction has occurred, often signifying the formation of an insoluble product.

Front

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

Back

A complete ionic equation shows all the ions present in the reaction, while a net ionic equation only shows the ions that participate in the reaction.
