34. Consider the following redox reaction: 2Cu2O (s) + Cu2S (s) —— 6Cu (s)
Consider the following redox reaction:
2Cu2O (s) + Cu2S (s) —— 6Cu (s) + SO2 (g)
Identify the species among the following acting as oxidant and reductant, respectively:
[amp_mcq option1=”Cu(I) and S of Cu2S” option2=”Cu and S of SO2″ option3=”Cu and O of SO2″ option4=”Cu(I) and O of SO2″ correct=”option1″]
This question was previously asked in
UPSC CAPF – 2023
In Cu₂O, Cu is +1, O is -2.
In Cu₂S, Cu is +1, S is -2.
In Cu, Cu is 0.
In SO₂, S is +4, O is -2.
Cu changes from +1 to 0, so it is reduced. The species causing reduction (oxidant) contains Cu(+1). Both Cu₂O and Cu₂S contain Cu(+1).
S changes from -2 (in Cu₂S) to +4 (in SO₂), so it is oxidized. The species causing oxidation (reductant) is Cu₂S, specifically the S atom within it.
Thus, Cu(I) acts as the oxidant and S of Cu₂S acts as the reductant.

– Statement 2 is correct: During a National Emergency, the executive power of the Union extends to giving directions to any State as to the manner in which its executive power is to be exercised (Article 353(a)).
– Statement 3 is correct: A proclamation of National Emergency does not suspend the State Legislature. State Legislatures continue to function normally, although Parliament acquires concurrent power to make laws on subjects in the State List (Article 250).
– Statement 4 is incorrect: While parliamentary approval makes the Proclamation continue for six months at a time (from the date of approval or subsequent approval), the initial Proclamation is valid for one month *without* parliamentary approval. The statement says it “can continue… only if approved”, which is not entirely accurate for the initial month. More importantly, it can be extended repeatedly for periods of six months after initial approval, implying continuation beyond the first six months is possible with repeated approvals. The phrasing “maximum period of six months at a time only if approved” refers to the duration granted by each approval, but the statement might be interpreted in ways that make it less precise than 1, 2, and 3. Given that 1, 2, and 3 are clearly correct and form an option, it’s most likely intended that 4 is not correct or less accurate in comparison.
