Net Ionic Equations

Front

What is a net ionic equation?

Back

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

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two aqueous solutions are mixed.

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 determine if a precipitate will form in a reaction?

Back

A precipitate will form if the product of the reaction is insoluble in water.

Front

What is the solubility rule for nitrates?

Back

All nitrates (NO3-) are soluble in water.

Front

What is the solubility rule for chlorides?

Back

Most chlorides are soluble, except for those of silver (Ag+), lead (Pb2+), and mercury (Hg2+).

Front

What is the solubility rule for sulfates?

Back

Most sulfates are soluble, except for those of barium (Ba2+), lead (Pb2+), and calcium (Ca2+).

Front

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

Back

Lead (II) chloride, a precipitate, forms when lead (II) nitrate is mixed with sodium chloride.

Front

What is the net ionic equation for the reaction between HBr and LiOH?

Back

H+(aq) + OH-(aq) → H2O(l)
