Question

A mixture of $Sn$ and $Pb$ can be separated by __________ method.

• A. hank picking
• B. distillation
• C. liquation
• D. winnowing

Answer 1

The correct option is C liquation

Liquation is a metallurgical method for separating metals from an ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected.

Tin has a lower melting point compared to Lead and hence, tin melts and flows and it is separated from lead.

Therefore a mixture of $Sn$ and $Pb$ can be separated by liquation method.
