Solubility and Precipitation Reactions

Front

What is a Precipitation Reaction?

Back

A chemical reaction where two aqueous solutions combine to form a solid, known as a precipitate.

Front

What is the precipitate in the reaction: Pb(NO3)2 (aq) + 2KI (aq) → PbI2 (s) + 2KNO3 (aq)?

Back

PbI2, which is the solid that does not dissolve in water.

Front

What notation is used to indicate a solid precipitate in a molecular equation?

Back

(s) for solid.

Front

What is an aqueous solution?

Back

Water with another compound dissolved in it.

Front

Which of the following compounds is soluble: copper carbonate, calcium carbonate, potassium carbonate, or strontium carbonate?

Back

Potassium carbonate, as it is always soluble.

Front

What is a solubility rule?

Back

Guidelines that predict whether a compound will dissolve in water.

Front

What does it mean if a compound is insoluble?

Back

It means that the compound does not dissolve in water.

Front

What is the role of a precipitate in a chemical reaction?

Back

It indicates that a reaction has occurred and helps in identifying the products.

Front

What is the difference between soluble and insoluble compounds?

Back

Soluble compounds dissolve in water, while insoluble compounds do not.

Front

What is the significance of the (aq) notation in chemical equations?

Back

It indicates that the substance is in an aqueous solution, meaning it is dissolved in water.
