Net ionic equations Practice

Front

What is a net ionic equation?

Back

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

Front

What is a precipitate?

Back

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

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 determine if a precipitate will form in a reaction?

Back

To determine if a precipitate will form, consult solubility rules to see if any of the products are 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 (Cl-) are soluble, except for those of silver (Ag+), lead (Pb2+), and mercury (Hg2+).

Front

What is the solubility rule for hydroxides?

Back

Most hydroxides (OH-) are insoluble, except for those of alkali metals and barium (Ba2+).

What is the balanced equation for the reaction of zinc nitrate and sodium hydroxide?

Back
