The position of some metals in the electropositive decreasing electropositive character is given as `Zn gt Cu gt Ag`. What will happen if a copper is to stir a solution of aluminium nitrate.

Options

A. The spoon will get coated with aluminium
B. An alloy of copper and aluminium is formed.
C. The solution becomes blue
D. There is no reaction.

Answer

To solve the question, we need to analyze the electropositive character of metals and their ability to displace one another in a chemical reaction. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Electropositive Character
The electropositive character of metals indicates their ability to lose electrons and form positive ions. In the given series, Zinc (Zn) is more electropositive than Copper (Cu), which is more electropositive than Silver (Ag). This means that Zinc can displace both Copper and Silver from their compounds, while Copper can only displace Silver.

**Hint:** Remember that a more electropositive metal can displace a less electropositive metal from its compound.

### Step 2: Refer to the Metal Activity Series
The metal activity series ranks metals based on their reactivity. The series is as follows (from most reactive to least reactive):
Potassium > Sodium > Calcium > Magnesium > Aluminum > Zinc > Iron > Tin > Lead > Hydrogen > Copper > Mercury > Silver > Gold.

In this series, Aluminum (Al) is above Copper (Cu), indicating that Aluminum is more reactive than Copper.

**Hint:** The position of metals in the activity series determines their ability to displace other metals from solutions.

### Step 3: Analyze the Reaction with Aluminum Nitrate
When Copper (Cu) is placed in a solution of Aluminum Nitrate (Al(NO3)3), we need to determine if a reaction will occur. For a reaction to take place, Copper must be able to displace Aluminum from the Aluminum Nitrate solution.

**Hint:** A metal can only displace another metal from its compound if it is higher in the activity series.

### Step 4: Determine the Outcome
Since Aluminum is above Copper in the activity series, Copper cannot displace Aluminum from Aluminum Nitrate. Therefore, no reaction will occur when Copper is stirred in a solution of Aluminum Nitrate.

**Hint:** If the metal you are testing is lower in the activity series than the metal in the compound, expect no reaction.

### Conclusion
In conclusion, when Copper is stirred in a solution of Aluminum Nitrate, there will be no reaction because Copper cannot displace Aluminum due to its lower position in the metal activity series.

**Final Answer:** No reaction will occur when Copper is placed in Aluminum Nitrate solution.
