Double Replacement Reactions

Front

What is a double replacement reaction?

Back

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

Front

What is a precipitate?

Back

An insoluble solid that forms when two aqueous solutions react.

Front

What happens when copper (II) nitrate and potassium hydroxide are mixed?

Back

The product is Cu(OH)2, which is a precipitate.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What indicates a double replacement reaction has occurred?

Back

The formation of a precipitate, gas, or water.

Front

What is the product of mixing magnesium nitrate and sodium hydroxide?

Back

The product is Mg(OH)2, which is a precipitate.

Front

What is the difference between soluble and insoluble substances?

Back

Soluble substances can dissolve in a solvent, while insoluble substances cannot.

Front

What is the role of water in double replacement reactions?

Back

Water can act as a solvent, allowing reactants to mix and react.

Front

What is the significance of balancing chemical equations?

Back

Balancing ensures that the law of conservation of mass is followed, meaning the number of atoms remains the same before and after the reaction.

Front

What does (aq) signify in a chemical equation?

Back

(aq) indicates that a substance is dissolved in water, forming an aqueous solution.
