Order the steps
Number the metals from 1 to 10 to show the correct reactivity series order. Number 1 = most reactive metal; Number 10 = least reactive metal.
| Order (1–10) | Metal |
|---|---|
| Iron (Fe) | |
| Potassium (K) | |
| Copper (Cu) | |
| Aluminium (Al) | |
| Zinc (Zn) | |
| Sodium (Na) | |
| Silver (Ag) | |
| Calcium (Ca) | |
| Magnesium (Mg) | |
| Lead (Pb) |
True or False? Fix the false ones
Circle T or F for each statement. If the statement is false, rewrite it correctly on the line below.
Copper will displace zinc from zinc sulfate solution because copper is higher in the reactivity series than zinc.
Correct it:
When zinc is placed in copper sulfate solution, the blue colour of the solution fades because copper is being deposited.
Correct it:
Galvanising coats iron with zinc to protect it from rust because zinc is less reactive than iron and acts as a barrier.
Correct it:
In a single displacement reaction, one element replaces another element in a compound.
Correct it:
1. A student places a piece of magnesium ribbon into copper sulfate solution. Predict what will happen, write the word equation, and state two observable changes that would indicate a displacement reaction has occurred.
2. Silver (Ag) is at the bottom of the reactivity series. Would silver displace copper from copper sulfate solution? Explain your reasoning using the reactivity series.
