Identify correct statement for reaction stated below. Ag ₂ O + H ₂ O +2 e 2 Ag +2 OH ⁻

Options

  1. AWater is oxidised.
  2. BHydrogen is oxidised.
  3. CSilver is reduced.
  4. DHydrogen is reduced.

Correct answer

C. Silver is reduced.

Step-by-step solution

The reaction is Ag ₂ O + H ₂ O + 2 e 2 Ag + 2 OH ⁻ . The oxidation state of silver in Ag ₂ O is +1, determined from 2(x) + (-2) = 0 x = +1 . In silver metal, the oxidation state is 0, indicating silver is reduced. Oxygen has an oxidation state of -2 in all species, and hydrogen is +1, with no change. The correct statement is that silver is reduced.
