Question 1.
What does the electrochemical series represent?
Show hintHide hint
Think of how metals react or 'give away' electrons.
Question 2.
What is a reducing agent?
Show hintHide hint
It is the opposite of an oxidizing agent.
3Question 3.
What role do reducing agents play in metallurgy?
- They donate electrons
- They accept electrons
- They don't participate
Show hintHide hint
Think about what happens during the reduction process.
4Question 4.
Electrolytic reduction is primarily used for:
- True
- False
Show hintHide hint
Recall the metals discussed in this context.
Question 5.
A chemist wants to extract magnesium from magnesium chloride (MgCl₂). Discuss the possible methods and outline the role of electrode potential in this process.
Show hintHide hint
Consider the position of magnesium in the electrochemical series compared to sodium and potassium.
Question 6.
Given two metals, lead (Pb) with an electrode potential of -0.13V and cobalt (Co) with -0.28V, determine which is the better reducing agent and explain your reasoning.
