Explanation:
The given reaction is a redox reaction as there is a change in oxidation states of Cu and C. To balance the redox reaction, we need to follow the below steps.
Step 1: Write the unbalanced equation
Cu(NH3)4Cl2 + KCN → K2Cu(CN)2 + NH3 + KCNO + NH4Cl + KCl
Step 2: Identify the oxidation states
Cu in Cu(NH3)4Cl2: +2
Cu in K2Cu(CN)2: +1
C in KCN: -1
C in KCNO: +2
Step 3: Split the reaction into half-reactions
Oxidation half-reaction: Cu → Cu+2 + 2e-
Reduction half-reaction: CN- + 1e- → CNO-
Step 4: Balance the half-reactions
To balance the oxidation half-reaction, we need to multiply it by 2.
2Cu → 2Cu+2 + 4e-
To balance the reduction half-reaction, we need to multiply it by 4.
4CN- + 4e- → 4CNO-
Step 5: Add the half-reactions together
2Cu + 4CN- + 4NH3 + 2Cl2 → 2Cu(CN)2 + 8NH3 + 2NO + 2NH4Cl
Step 6: Balance the equation
2Cu(NH3)4Cl2 + 4KCN → K2Cu(CN)2 + 2NH3 + 2KCNO + 2NH4Cl + 2KCl
Therefore, the balanced redox equation is: 2Cu(NH3)4Cl2 + 4KCN → K2Cu(CN)2 + 2NH3 + 2KCNO + 2NH4Cl + 2KCl.
