Write the Equation for Treatment of Ag with CN^-

question 14

Multiple Choice

Write the equation for treatment of Ag with CN^-.

• A) 4 Ag(s) + 2 CN^- + O₂(g) + 2 H₂O(l) → 4 AgO(s) + 4 CO(g) + 4 NH^-
• B) 4 Ag(s) + 8 CN^- + O₂(g) + 2 H₂O(l) → 4 [AgCN]^- + 4 CO(g) + 4 NH⁺
• C) 4 Ag(s) + 8 CN^- + O₂(g) + 2 H₂O(l) → Ag₃N(s) + 4 OH^- + AgC₈(s)
• D) 4 Ag(s) + 8 CN^- + O₂(g) + 2 H₂O(l) → 4 [Ag(CN)₂]^- + 4 OH^-
• E) 4 Ag(s) + 8 CN^- + O₂(g) + 2 H₂O(l) → 4 AgO(s) + 2 H₂(g) + 2 CO + 6 CN^-
