Reactivity and Displacement of Metals

The video tutorial by Ms. Cam explains the activity series, which ranks metals based on their strength as reducing agents. Metals at the top are stronger reducing agents and more readily oxidized, while those at the bottom are weaker. The tutorial covers reactions involving magnesium, zinc, copper, and silver, illustrating how more reactive metals can displace less reactive metal ions from solutions. The video concludes with a summary emphasizing that more reactive metals are stronger reducing agents and can displace ions of less reactive metals.

What does the activity series rank metals by?

• Their atomic number

• Their strength as reducing agents

• Their density

• Their melting point

Which metals are more readily oxidized according to the activity series?

• All metals equally

• Metals in the middle

• Metals at the bottom

• Metals at the top

In a reaction between magnesium and copper sulfate, what happens to magnesium?

• It is reduced

• It is oxidized

• It remains unchanged

• It forms a gas

Why can zinc displace copper ions from a solution?

• Zinc is a weaker reducing agent

• Copper is a stronger reducing agent

• Zinc is a stronger reducing agent

• Copper is more reactive

What forms on zinc when it is placed in a copper sulfate solution?

• Zinc metal

• Copper sulfate

• Copper metal

• Zinc sulfate

What happens when copper is added to a zinc sulfate solution?

• Zinc displaces copper

• No reaction occurs

• Copper displaces zinc

• Copper sulfate forms

In a reaction with silver nitrate, what does copper do?

• It remains unchanged

• It displaces silver ions

• It forms copper oxide

• It is oxidized

Why does silver not react with copper nitrate solution?

• Silver is a weaker reducing agent

• Silver is a stronger reducing agent

• Copper is more reactive

• Copper is a weaker reducing agent

Where are stronger reducing agents found in the activity series?

• At the top

• In the middle

• They are not in the series

• At the bottom

What can more reactive metals do to less reactive metal ions in solution?

• They can form alloys with them

• They can dissolve them

• They can oxidize them

• They can displace them
