Solubility Rules and Precipitation Reactions

Front

What are solubility rules?

Back

Solubility rules are guidelines used to predict whether a given ionic compound will dissolve in water.

Front

What does it mean for a compound to be soluble?

Back

A soluble compound is one that dissolves in water, forming a homogeneous solution.

Front

What does it mean for a compound to be insoluble?

Back

An insoluble compound does not dissolve significantly in water, often forming a precipitate.

Front

What is a precipitation reaction?

Back

A precipitation reaction occurs when two solutions are mixed, resulting in the formation of an insoluble solid (precipitate).

Front

What is the general rule for the solubility of nitrates (NO3-) in water?

Back

Nitrates are generally soluble in water.

Front

What is the general rule for the solubility of carbonates (CO3^2-) in water?

Back

Most carbonates are insoluble in water, except for those of alkali metals and ammonium.

Front

Which compound is soluble: copper carbonate, calcium carbonate, potassium carbonate, or strontium carbonate?

Back

Potassium carbonate is soluble.

Front

What is the precipitate formed when MgCO3 and Fe2(SO4)3 are mixed?

Back

Fe2(CO3)3 is the precipitate formed.

Front

In the reaction Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq), which ion is not present in the complete ionic equation?

Back

All the above ions (Pb^2+, K+, NO3-, I-) are present in the complete ionic equation.

What is the solubility of lead(II) iodide (PbI2) in water?

Back

Lead(II) iodide (PbI2) is insoluble in water.
