Question

In the following chemical reaction: ${Ag_2O + H_2O + 2e^{-} -> 2Ag + 2OH^{-}}$

• A. Hydrogen is reduced
• B. Electrons are reduced
• C. Water is oxidised
• D. Silver is oxidised

Answer 1

Answer: (C)

Water is oxidised

Answer 2

In the given reaction, water is being oxidised because it is accepting oxygen from ${Ag2O}$, while ${Ag^{+}}$ is reduced. ${Ag_2O + H_2O + 2e^{-} -> 2Ag + 2OH^{-}}$
