Oxidising & Reducing Agents Table
A visual reminder of oxidation numbers and redox. This is like an elevator in a building going up to higher floors is oxidation and going down to the basement is reduction
Four reactions are shown. In which reaction is the species in blue acting as an oxidising agent?
A. Cr2O72- + 8H+ + 3SO32- → 2Cr3+ + 4H2O+ 3SO42-
B. Mg + Fe2+ → Mg2+ + Fe
C. Cl2 + 2Br- → 2Cl- + Br2
D. Fe2O3 + 3CO → 2Fe + 3CO2
Answer:
The correct option is B.
