Reactivity of Copper with Acids

The video tutorial explores the potential reaction between hydrochloric acid (HCl) and copper (Cu). Initially, it suggests a possible single replacement reaction where copper could displace hydrogen. However, using the activity series of metals, it is determined that copper is less reactive than hydrogen, meaning no reaction occurs. The video also notes that under specific conditions, such as adding H2O2, a reaction might take place. The activity series is highlighted as a useful tool for predicting single displacement reactions.

What is the initial hypothesis when hydrochloric acid reacts with copper?

• Copper will not react at all.

• Copper will form a precipitate with hydrochloric acid.

• Copper will replace hydrogen in a single replacement reaction.

• Copper will dissolve in hydrochloric acid.

What tool is used to determine the reactivity of metals?

• Reactivity Chart

• Activity Series

• Periodic Table

• Metallic Bonding Table

Where is copper located in the activity series relative to hydrogen?

• Above hydrogen

• Below hydrogen

• Not on the activity series

• At the same level as hydrogen

What conclusion is drawn about the reaction between hydrochloric acid and copper?

• No reaction occurs.

• A gas is produced.

• A slow reaction occurs.

• A vigorous reaction occurs.

How can a reaction be induced between copper and hydrochloric acid?

• By increasing the pressure
