Question

The following reaction is used to produce chromium metal at high temperature.Cr₂O₃(s) + 2Al(s) $\rarr$ 2Cr(l) + Al₂O₃(s) Which element is oxidized and which is reduced

Quizplus · Accepted Answer

In the given reaction, aluminum (Al) loses electrons (is oxidized) and chromium (Cr) gains electrons (is reduced). This is because aluminum starts as a pure element and ends up in a compound, indicating it has lost electrons. Conversely, chromium starts in a compound and ends up as a pure element, indicating it has gained electrons.
