Precipitation Reactions

Front

What is a precipitate?

Back

A precipitate is a solid that forms when two liquids react together.

Back

Insoluble

Front

What is the process called when solutions of two ionic compounds are combined and a solid forms?

Back

Precipitation

Front

Is KBr soluble or insoluble?

Back

Soluble

Front

What is the general equation for a precipitation reaction?

Back

AB + CD → AD + CB (where AB and CD are soluble ionic compounds, and AD is the precipitate).

Front

What factors affect the formation of a precipitate?

Back

Concentration of reactants, temperature, and the presence of other ions.

Front

What is the role of solubility rules in predicting precipitation reactions?

Back

Solubility rules help determine which ionic compounds will remain in solution and which will form a precipitate.

Front

What is the difference between soluble and insoluble compounds?

Back

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

Front

What is an example of a common precipitate?

Back

Barium sulfate (BaSO₄) is a common precipitate formed in reactions involving barium ions.
