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 in solution.

Front

How do you identify a precipitate in a reaction?

Back

A precipitate is identified as a solid that forms and separates from a solution during a chemical reaction.

Front

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

Back

Ag+(aq) + Cl-(aq) → AgCl(s)

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

Back

Lead (II) chloride (PbCl2) forms as a precipitate.

Front

Which ions are present in the solution after the reaction of sodium chloride with silver nitrate?

Back

Sodium (Na+) and nitrate (NO3-) are the spectator ions.

Front

What is the role of a precipitate in a double displacement reaction?

Back

The formation of a precipitate indicates that a reaction has occurred, as it shows that certain ions have combined to form an insoluble compound.

Front

What is the significance of balancing chemical equations?

Back

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

Front

What is the formula for lead (II) chloride?

Back

The formula for lead (II) chloride is PbCl2.

Front

What happens to the ions in a solution when a precipitate forms?

Back

When a precipitate forms, the ions that combine to form the precipitate are removed from the solution.
