Unit 8 Exit Ticket #6 Double Displacement Reactions

Front

What is a double displacement reaction?

Back

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

Front

What is the general form of a double displacement reaction?

Back

The general form is: AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What is a precipitate in a chemical reaction?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What are the common indicators of a double displacement reaction?

Back

Common indicators include the formation of a precipitate, gas, or a weak electrolyte like water.

Front

What happens when CaCl2 reacts with NaOH?

Back

The reaction produces Ca(OH)2, which is a precipitate.

Front

Will NaOH react with KCl? Why or why not?

Back

No, the reaction will not occur because both NaOH and KCl are soluble in water and do not form a precipitate.

Front

What is the result of the reaction between Cu(NO3)2 and K2SO4?

Back

The reaction occurs and produces CuSO4 and KNO3, with CuSO4 being a precipitate.

Front

What is the role of solubility rules in predicting double displacement reactions?

Back

Solubility rules help determine whether a precipitate will form when two ionic compounds are mixed.

Front

What is the significance of balancing chemical equations in double displacement reactions?

Back

Balancing chemical equations ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides.

Front

What is the difference between soluble and insoluble compounds?

Back

Soluble compounds dissolve in water, while insoluble compounds do not dissolve significantly and may form a precipitate.
