Question

01 Question (2 points) See page 181 If a nail made of elemental iron [Fe(s) is placed in an aqueous solution of a soluble palladium(II) salt [Pd?"all, the nail will gradually disappear as the iron enters the solution as Fed(aq) and palladium metal [Pd(s) forms. 1st attempt Part 1 (1 point) IW See Periodic Table O See Hint Is this a redox equation? Choose one: Yes No

Answer 1

​​​​​​Answer 1):-

Part 1:-

Yes, it is redox reaction. The elemental Fe [oxidation state = 0] get oxidized to Fe³⁺ , while the Pd²⁺ is reduced to Pd.

--------------------------------------------

Part 2:-

[ Fe (s) $\rightarrow$ Fe³⁺ (aq) + 3e^- ] × 2   (Oxidation)

[Pd²⁺ (aq) + 2e^- $\rightarrow$ ​​​​​ Pd (s) ] × 3 (Reduction)

Thus,

Balanced net ionic equation:-

2 Fe​​​​​​​ (s) + 3 Pd²⁺ (aq)  $\rightarrow$ 2 Fe³⁺ (aq) + 3 Pd (s)
