C3.3.1 Oxidation and Reduction

Cards (24)

  • What are oxidation and reduction in terms of electron transfer?
    Electron transfer processes
  • Reduction is a reaction where a substance gains electrons.

    True
  • A reducing agent is a substance that donates electrons
  • What happens to a substance during reduction in terms of electron transfer?
    Gains electrons
  • Oxidizing agents are necessary for oxidation to occur because they remove electrons from the substances being oxidized.

    True
  • What is the key feature of a redox reaction?
    Electron transfer
  • Match the reducing agent with its example:
    Hydrogen ↔️ H₂
    Carbon ↔️ C
    Sodium ↔️ Na
  • Oxidizing agents facilitate oxidation by providing electrons.
    False
  • Oxidation involves the loss of electrons
  • What happens to zinc in the reaction with copper sulfate?
    Zinc loses electrons
  • Steps to solve chemical equations involving redox reactions
    1️⃣ Identify oxidation and reduction processes
    2️⃣ Recognize the redox reaction
    3️⃣ Determine the oxidizing and reducing agents
  • In the reaction between zinc and copper sulfate, copper sulfate acts as the oxidizing agent
  • Oxidation is a reaction where a substance loses electrons
  • What is an oxidizing agent in terms of electron transfer?
    Accepts electrons
  • Match the oxidizing agent with its example:
    Oxygen ↔️ O₂
    Chlorine ↔️ Cl₂
    Hydrogen peroxide ↔️ H₂O₂
  • An oxidizing agent causes oxidation by accepting electrons
  • Steps in a redox reaction
    1️⃣ Oxidation: Substance loses electrons
    2️⃣ Reduction: Substance gains electrons
  • In the reaction between zinc and copper sulfate, zinc loses electrons and undergoes oxidation
  • Redox reactions are fundamental in many chemical and biological systems.
