In the reaction
\(\mathrm{CuO + H_2 \rightarrow Cu + H_2O}\), which reactant is the reducing agent?अभिक्रिया
\(\mathrm{CuO + H_2 \rightarrow Cu + H_2O}\)
में कौन-सा अभिकारक अपचायक है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Hydrogenहाइड्रोजन
Hydrogen removes oxygen from \(\mathrm{CuO}\), converting it to copper \(\mathrm{Cu}\); therefore, \(\mathrm{H_2}\) is the reducing agent. Hydrogen is itself oxidised to \(\mathrm{H_2O}\). In contrast, \(\mathrm{CuO}\) is reduced, so it is the oxidising agent rather than the reducing agent.हाइड्रोजन \(\mathrm{CuO}\) से ऑक्सीजन हटाकर उसे तांबे \(\mathrm{Cu}\) में बदल देता है; इसलिए \(\mathrm{H_2}\) अपचायक है। \(\mathrm{H_2}\) स्वयं ऑक्सीकरण होकर \(\mathrm{H_2O}\) बनता है। इसके विपरीत, \(\mathrm{CuO}\) अपचयित होता है, इसलिए वह ऑक्सीकारक है, अपचायक नहीं।
