Q. Show the Liquation in purification of metals?
Crude tin, bismuth and lead are purified by liquation. In this process, the impure metal is placed at the top of a sloping hearth maintained at a temperature slightly above the melting point of the metal. The metal melts and flows down the inclined hearth into a well leaving at the back the solid impurities.
The quantity of substance liberated, dissolved, or deposited at an electrode is directly proportional to the quantity of electricity passed by the electrolyte.
