Is 2Fe(s) + 3NiCl2 (aq) —> 2FeCl3(aq) + 3Ni(s) a redox reaction? If so, what is the reducing agent and what is the oxidizing agent
Yes, the reaction 2Fe(s) + 3NiCl2(aq) -> 2FeCl3(aq) + 3Ni(s) is a redox reaction. In this reaction, iron (Fe) is being oxidized and nickel (Ni) is being reduced.
The reducing agent is Fe, as it is losing electrons and being oxidized from an oxidation state of 0 to +3 in FeCl3. The oxidizing agent is NiCl2, as it is gaining electrons and being reduced from an oxidation state of +2 to 0 in Ni.
