How are tin and lead purified ?

Explanation

To purify tin and lead, we can use a method called "fractional melting" or "zone refining." Here’s a step-by-step breakdown of the process:

### Step 1: Understanding the Properties
- **Tin and Lead Characteristics**: Both tin and lead are low melting point metals. Tin has a melting point of approximately 505 K, while lead has a melting point of about 600 K. This property is crucial for the purification process.

### Step 2: Setting Up the Apparatus
- **Slope Type Setup**: We will use a slope-type apparatus. This setup allows the molten metal to flow downwards while keeping the impurities separated.
