Per NCERT §7.3.2 (half-reaction method) for a BASIC medium, oxygen balance is achieved by adding which species?
AUse only H₂O on both sides
BUse only OH⁻ ions throughout
CUse H⁺ and OH⁻ together explicitly
DAdd H₂O on one side and OH⁻ on the other
Answer & Solution
Correct answer: D. Add H₂O on one side and OH⁻ on the other
NCERT §7.3.2(b): basic medium — add H₂O and OH⁻ pairs to balance O and H without using H⁺.
