Single Replacement Reactions

Front

What is a single replacement reaction?

Back

A chemical reaction where one element replaces another in a compound.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B

Front

What determines if a single replacement reaction will occur?

Back

The reactivity of the elements involved, often determined by the activity series.

Front

What is the activity series?

Back

A list of metals ranked by their reactivity, used to predict the outcomes of single replacement reactions.

Front

Which is more reactive: Potassium (K) or Sodium (Na)?

Back

Potassium (K) is more reactive than Sodium (Na).

Front

What happens when a more reactive metal is placed in a solution of a less reactive metal's salt?

Back

A single replacement reaction occurs, and the more reactive metal displaces the less reactive metal.

Front

What are the products of the reaction: Zn + CuSO4?

Back

Cu + ZnSO4

Front

What is the result of the reaction: Cl2 + 2KI?

Back

2KCl + I2

Front

What is the significance of the halogen activity series?

Back

It helps predict whether a halogen can replace another halogen in a compound.

Front

What is the outcome of the reaction: Au + HCl?

Back

No Reaction, as gold (Au) is less reactive than hydrogen.
