Precipitation Reactions & Net Ionic Equations

Front

What is an aqueous solution?

Back

An aqueous solution is water with another compound dissolved in it.

Front

Why does no reaction occur when copper and magnesium sulfate are mixed?

Back

Magnesium is more reactive than copper.

Front

What is the formula of the precipitate formed when Pb(NO3)2(aq) and K2SO4(aq) are mixed?

Back

PbSO4.

Front

Which reaction results in the formation of a precipitate: AgNO3(aq) + NaOH(aq)→, BaNO3(aq) + CaCl2(aq)→, NaNO3(aq) + KOH(aq)→?

Back

AgNO3(aq) + NaOH(aq)→.

Front

Which of the following does NOT form a precipitate: Pb(NO3)2(aq) + 2KI(aq)→, Sr(NO3)2(aq) + K2SO4(aq)→, AgNO3(aq) + Na2S(aq)→, Pb(NO3)2(aq) + AgNO3(aq)→?

Back

Pb(NO3)2(aq) + AgNO3(aq)→.

Front

What is a precipitate?

Back

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

Front

What is a net ionic equation?

Back

A net ionic equation shows only the species that participate in a 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.

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.

Front

What is the role of solubility rules in precipitation reactions?

Back

Solubility rules help predict whether a precipitate will form when two ionic compounds are mixed.
