Iupac what even is 919-917= 2
+2 is you're answer for question number 5
Answer;
Silver is acting as oxidizing Agent.
Explanation:
The reaction is as follow,
<span> Fe + 3 AgNo</span>₃ → Fe(NO₃)₃<span> + 3 Ag
In above reaction the Iron's oxidation state has changed from 0 to +3, i.e.
Fe</span>⁰ → Fe³⁺ + 3 e⁻
It shows that Iron has lost 3 electrons, Hence, it is oxidized and has transferred 3 electrons to 3 mole of Ag⁺ to reduce it into Ag. Therefore, Iron is acting as reducing Agent.
While, In reaction the Silver's oxidation state has changed from +1 to 0, i.e.
3 Ag⁺ + 3 e⁻ → 3 Ag
It shows that Silver has gained one electron, Hence, it is reduced and has gained 3 electrons from 1 mole of Fe to oxidize it into Fe³⁺. Therefore, Silver is acting as oxidizing Agent.
