Refining using liquation method is the most suitable for metals with: (1) Low melting point (2) High boiling point (3) High electrical conductivity (4) Less tendency to be soluble in melts than impurities

1. (1) Low melting point
2. (2) High boiling point
3. (3) High electrical conductivity
4. (4) Less tendency to be soluble in melts than impurities

Correct answer: (2) High boiling point

Solution

The liquation method is effective for metals with a high boiling point because it allows for the separation of the metal from impurities by melting the mixture and taking advantage of the differences in boiling points, ensuring that the desired metal remains in the liquid phase while impurities are left behind.
