Precipitation Reactions

Front

What is a precipitation reaction?

Back

A precipitation reaction is a chemical reaction in which two soluble salts react in solution to form an insoluble salt, known as a precipitate.

What type of compounds does water dissolve best?

Back

Water is particularly good at dissolving ionic compounds.

Front

What is the charge of a cation?

Back

A cation has a positive charge.

Front

What is the charge of an anion?

Back

An anion has a negative charge.

Front

What happens when cations and anions react?

Back

Cations and anions react to form new compounds.

Front

What is the chemical formula for silver nitrate?

Back

The chemical formula for silver nitrate is AgNO₃.

Front

What is a common example of a precipitate?

Back

A common example of a precipitate is barium sulfate (BaSO₄), which forms when barium ions react with sulfate ions.

Front

What is the role of water in precipitation reactions?

Back

Water acts as a solvent that allows ionic compounds to dissociate into their respective ions, facilitating the reaction.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, typically expressed in grams of solute per 100 grams of solvent.

Front

What is the significance of the periodic table in understanding ionic compounds?

Back

The periodic table helps identify elements that form cations (usually metals) and anions (usually nonmetals), which are essential for forming ionic compounds.
