Predicting Products - Double Replacement & Insolubility

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two solutions are mixed and a chemical reaction occurs.

Front

How can you predict if a precipitate will form in a double replacement reaction?

Back

You can predict if a precipitate will form by using solubility rules to determine if any of the products are insoluble in water.

Front

What are solubility rules?

Back

Solubility rules are guidelines that help predict whether a compound will dissolve in water or form a precipitate.

Front

What is the solubility of AgCl in water?

Back

AgCl is insoluble in water, meaning it will precipitate out of solution.

Front

What are the products of the reaction NaOH + MgSO3?

Back

The products are Mg(OH)2 + Na2SO3.

Front

Which compound is a common precipitate formed in reactions involving lead?

Back

PbI2 is a common precipitate formed in reactions involving lead.

Front

What is the role of KOH in acid-base reactions?

Back

KOH acts as a strong base that can neutralize acids to form water and a salt.

Front

What is the product of the reaction KOH + H3PO4?

Back

The products are K3PO4 + HOH.

Front

What is the significance of identifying precipitates in chemical reactions?

Back

Identifying precipitates helps in understanding the reaction's outcome and the formation of new compounds.
