Chemical Reactions Involving Metals: Oxidation, Reduction, and Redox Reactions

The video tutorial covers chemical reactions involving metals, focusing on oxidation, reduction, and redox reactions. It explains the reactivity of various metals with water and acids, highlighting the tendency of more reactive metals to form positive ions. The tutorial also discusses displacement reactions, providing examples with zinc, copper, and silver to illustrate how more reactive metals can displace less reactive ones from compounds.

What happens to a compound when it loses oxygen?

• It is oxidized

• It is reduced

• It becomes an acid

• It forms a gas

Which metal reacts most vigorously with water?

• Potassium

• Calcium

• Magnesium

• Copper

Which metal does not react with water or acids?

• Zinc

• Iron

• Magnesium

• Copper

In a displacement reaction, what happens when zinc is added to copper sulfate solution?

• Copper displaces zinc

• No reaction occurs

• Zinc displaces copper

• Zinc and copper form an alloy

Why does no reaction occur when silver is placed in copper nitrate solution?

• Silver is more reactive than copper

• Copper is more reactive than silver

• Both metals are equally reactive

• Silver forms a protective layer
