Total and Net Ionic Equations

Front

What is a total ionic equation?

Back

A total ionic equation shows all the ions present in a reaction, including spectator ions that do not participate in the actual chemical change.

Front

What is a net ionic equation?

Back

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

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the 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 total ionic equation. 2. Identify and remove spectator ions. 3. Write the remaining species as the net ionic equation.

Front

What is the significance of a precipitate in a reaction?

Back

A precipitate indicates that a chemical reaction has occurred, resulting in the formation of an insoluble product.

Front

What is the solubility rule for most sulfates?

Back

Most sulfates are soluble in water, except for those of barium, lead, and calcium.

Front

What happens when lead (II) nitrate reacts with sodium chloride?

Back

Lead (II) chloride precipitate forms as a result of the reaction.

Front

What is the net ionic equation for the reaction of AgNO3 and CaCl2?

Back

Ag+(aq) + Cl-(aq) → AgCl(s) is the net ionic equation.

Front

What is the result of mixing potassium bromide and ammonium sulfide?

Back

No precipitate is formed when potassium bromide and ammonium sulfide are mixed.

Front

What is the role of Ba2+ in the reaction with (NH4)2SO4?

Back

Ba2+ combines with SO4^2- to form the insoluble precipitate BaSO4.
