Which one of the following is most likely a mismatch ?

The most likely mismatch among the given options is : Zinc - Liquation. <br/><br/> Liquation is a process of refining metals that involves melting the metal at a temperature slightly below its melting point and allowing it to cool slowly. This causes impurities to separate out as they solidify at different temperatures from the main metal. Liquation is typically used for metals with low melting points, such as tin and lead. <br/><br/> Zinc, on the other hand, has a relatively high melting point of 419.53 °C. Therefore, it is unlikely that zinc would be refined using the liquation process. Instead, zinc is commonly produced through the electrolysis of its ores or by distillation in the retort process. <br/><br/> On the other hand, the other options are more likely to be matched with their respective refining processes:<br/><br/> - Titanium is commonly refined using the van Arkel method, which involves the reaction of titanium tetrachloride with a metal like sodium or magnesium to form a volatile titanium compound that can be purified through fractional distillation.<br/><br/> - Nickel is commonly refined using the Mond process, which involves the reaction of nickel with carbon monoxide to form a volatile nickel carbonyl compound that can be purified through fractional distillation.<br/><br/> - Copper is commonly refined using electrolysis, which involves the use of an electric current to separate copper from other metals in an electrolyte solution. <br/><br/> Therefore, the most likely mismatch among the given options is Option B - Zinc - Liquation.
