Question 1.
What is the definition of oxidation?
Show hintHide hint
Think about losing what electrons signify.
Question 2.
What does a reduction half-equation show?
Show hintHide hint
Where do you see the electrons appearing in reduction?
3Question 3.
What defines oxidation in modern chemistry?
- Gain of electrons
- Loss of electrons
- Neither
Show hintHide hint
Think about what happens during oxidation.
4Question 4.
True or False: The reducing agent gains electrons.
- True
- False
Show hintHide hint
Relate it to the definition of a reducing agent.
Question 5.
Consider the redox reaction: H₂ + Cl₂ → 2HCl. Identify the half-equations for the oxidation and reduction processes.
Show hintHide hint
Start by identifying what is being oxidized and reduced.
Question 6.
You have the reaction 2MnO₄⁻ + 10e⁻ + 16H⁺ → 2Mn²⁺ + 8H₂O. Show how to derive this from half-equations.
Show hintHide hint
Remember to find the half-equations first.
