Predicting Products in Double Replacement Reactions Using Solubility Rules

Front

What is a double replacement reaction?

Back

A chemical reaction where two compounds exchange ions to form two new compounds.

Front

What are solubility rules?

Back

Guidelines used to predict whether an ionic compound will dissolve in water.

Front

What does it mean if a compound is soluble in water?

Back

It means the compound can dissolve in water to form a solution.

Front

What does it mean if a compound is insoluble in water?

Back

It means the compound does not dissolve in water and may form a precipitate.

Front

What is a precipitate?

Back

An insoluble solid that forms when two solutions react.

Front

Which compounds are always soluble according to solubility rules?

Back

Compounds containing alkali metal cations (Group 1) and ammonium (NH4+).

Front

Are nitrates (NO3-) soluble or insoluble?

Back

Nitrates are always soluble in water.

Front

What happens when a soluble compound reacts with an insoluble compound?

Back

A precipitate may form as a result of the reaction.

Front

What is the solubility of hydroxides (OH-) in water?

Back

Hydroxides are generally insoluble, but are soluble when combined with alkali metals.

Front

What is the solubility of sulfates (SO4^2-) in water?

Back

Sulfates are generally soluble, except for those of barium, lead, and calcium.
