Reactivity Series: Displacement Reactions and Oxidation-Reduction Reactions

The video tutorial covers the concept of displacement reactions within the context of the reactivity series. It begins with an introduction to displacement reactions, followed by a detailed example involving copper sulfate and an iron nail. The tutorial explains how more reactive metals displace less reactive metals from their compounds, using the reactivity series as a guide. It also discusses the role of non-metals like carbon and hydrogen in displacing metals. The video concludes with an explanation of oxidation and reduction processes, emphasizing the gain and loss of oxygen in chemical reactions.

What happens to the color of the copper sulfate solution when an iron nail is placed in it?

• It remains blue.

• It turns red.

• It becomes colorless.

• It turns green.

In the reaction between copper sulfate and iron, what compound is formed with iron?

• Iron sulfate

• Iron nitrate

• Iron chloride

• Iron oxide

Why does iron displace copper from copper sulfate?

• Copper and iron have the same reactivity.

• Iron is more reactive than copper.

• Iron is less reactive than copper.

• Copper is more reactive than iron.

What happens when magnesium tries to displace lithium from lithium oxide?
