Mond's process class 12
WebMond process is the technique of refining Nickel which is an example of vapor phase refining. In the vapor phase refining metals are converted to their volatile compounds where the impurities remain unaffected during the formation of compounds. Metal can easily be recovered as the volatile compounds are easily decomposable. WebHere are there types system development models for instance Waterfall model, Spherical Model Prototyping Model. 1.Waterfall Model . The Waterfall Model was the first Process Model to be introduced.

Web25 sep. 2024 · (a)Mond’s process: When impure nickel is heated is a current of CO at 330-350 K, it forms volatile nickel tetracarbonyl complex leaving behind the impurities. The complex then heated to a higher temperature (450-470K) when it undergoes thermal decomposition giving pure nickel. WebSolution. Mond process for refining nickel: 1. In this process, nickel is heated in a stream of carbon monoxide forming a volatile complex, nickel tetracarbonyl. 2. The nickel carbonyl complex is subjected to higher temperature so that it is decomposed giving the pure metal. Concept: Electrochemical Principles of Metallurgy.
WebPrinciple of zone refining. The principle of zone refining is that the impurities in an ingot or ore of metal are more soluble in the melt state when compared to the corresponding solid-state of the impurities. In the zone refining process, the impurities are concentrated at one end of the block of metal so that the rest of the block is purified. WebMond process for refining of Nickel is based on the principle that nickel is heated in the presence of carbon monoxide to form nickel tetracarbonyl, which is a volatile complex. Ni + 4CO Ni(CO)4 (Nickel tetracarbonyl) Then, the obtained nickel tetracarbonyl is decomposed by subjecting it to a higher temperature (450 - 470 K) to obtain pure nickel metal.
