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 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

What is a precipitate?

Back

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

Front

How do you identify a precipitate in a reaction?

Back

A precipitate can be identified by observing the formation of a solid when two solutions are mixed, often indicated by a color change or cloudiness.

What is the solubility rule for chlorides?

Back

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

Front

What is the solubility rule for sulfates?

Back

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

Front

What is the solubility rule for hydroxides?

Back

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

Front

What is the balanced equation for the reaction of AgNO3 and NaCl?

Back

AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq).

Front

What is the net ionic equation for the reaction of lead (II) nitrate and sodium chloride?

Back

Pb2+(aq) + 2Cl-(aq) → PbCl2(s).

Front

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

Back

Zn2+(aq) + 2OH-(aq) → Zn(OH)2(s).
