Show hintHide hint
Think about what happens during the reaction.
Question 2.
What does the reddish-brown substance on the iron nail represent?
Show hintHide hint
Consider what metal is present in the copper sulphate.
3Question 3.
What is the color of the copper sulphate solution before placing the iron nail in it?
- Green

- True
- False
Show hintHide hint
Think about the reactivity series.
Question 5.
An iron nail is dipped into a mixture of copper sulphate and zinc sulphate solution. Predict the outcome and explain why?
Show hintHide hint
Reference the reactivity series to analyze the order of metals.
Question 6.
If the experiment is repeated with a piece of gold instead of iron, what will happen? Discuss your reasoning based on reactivity.
Show hintHide hint
Just like the previous problem, check the metal's position in the reactivity series.
