Single & Double Displacements

Question 1

Single Displacement Reactions

Answer 1

• Occurs when one element replaces another similar element in a compound
• AB + C —-> A + BC

Question 2

Double Displacement Reactions

Answer 2

• Involves the exchange of cations between two aqueous ionic compounds
• Many double displacement reactions involve the formation of a precipitate
• If a double displacement reaction results in two aqueous solutions, no reaction has actually taken place
• AB + CD —-> AD + CB

Question 3

What is a precipitate?

Answer 3

An insoluble solid that separates from a solution after a reaction

Question 4

What are neutralization reactions?

Answer 4

There are a special type of double displacement reaction where can acid and a base combine to produce water and a salt

Question 5

What do neutralization reactions of carbonate compounds produce?

Answer 5

They produce water and carbon dioxide because carbonic acid is unstable and decomposes
