Question

Fe(s)+ 2 HC2H3O2(aq) → Fe(C2H3O2)2(aq) + H2(g) Which substance is reduced and which subject is oxidized?

Answer 1

Answer:

- Iron is oxidized from 0 to +2.

- Hydrogen is reduced from +1 to 0.

Explanation:

Hello,

In this case, for the given reaction, we must first indicate the oxidation state of each element (notice that HC2H3O is acetic acid)

$Fe ^0(s)+ 2 H^+(C_2H_3O_2)^-(aq) \rightarrow Fe^{2+}(C_2H_3O_2)_2^-(aq) + H_2^0(g)$

Thereby, notcing that iron is alone at the beginning, it has zero as its oxidation state, but once the reaction is undergone, it changes to +2, moreover, the displaced hydrogen in the acetic acid is with +1 but after the chemical reaction it becomes alone for which its oxidation state is 0, thereby, we find that:

- Iron is oxidized from 0 to +2.

- Hydrogen is reduced from +1 to 0.
