Scientific Serendipity In 1890 Ludwig Mond, was investigating the rapid corrosion of nickel valves used in apparatus for theSolvay process*, and discovered Ni(CO) 4. 0. Mond 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. Carbon monoxide (co) is used as a purifying gas in mond's process to produce nickel from its ores. The Mond process, sometimes known as the carbonyl process is a technique created by Ludwig Mond in 1890 to extract and purify nickel. The Mond process is used for which one of the following: (a) chemical vapor deposition of silicon nitride onto silicon, (b) an electroplating process, (c) physical vapor deposition for coating TiN onto cutting tools, or (d) reducing nickel carbonyl to metallic Ni? So what we do is we put carbon monoxide and the nickel for with complex with this carbon monoxide which react with four carbon monoxide. He has drawn a plot by considering the temperature in the x-axis and the standard free energy change for the formation of metal oxide in y-axis. The temperature is then raised to 250°C which redeposits the pure nickel netal.
