A. Oxygen
B. Hydrogen
C. Nascent oxygen[O]
D. Nascent hydrogen[H]
¨ The combination of K2Cr2O7 and H2SO4 generates nascent oxygen [O]. This is because the reaction between K2Cr2O7 and H2SO4 results in the formation of chromic acid (H2CrO4), which is a strong oxidizing agent that can release nascent oxygen in the presence of reducing agents.
