when iron III oxide reacts with vinegar? Is either of the materials reduced or oxidized?
Vinegar is not oxidized or reduced right ? Because it still has an oxidation state of negative 1?
The only thing that is reduced is Fe because it now has an oxidation state of positive 2 instead of 3?
Let's go over what you wrote. I really don't understand how you came up with vinegar changing by -1. Nor how Fe changed from 3 to 2.
When iron(III) oxide and acetic acid(vinegar) are mixed there is no reaction. The oxide may dissolve, albeit slowly, but there really is no reaction. So if there is no reaction there can be no oxidation or reduction. Also, I want to correct your thinking on that last sentence you wrote. You may NOT have just one; if you have oxidation you MUST have something reduced simultaneously.
Hello, I am an art student working with vinegar and iron. I pour vinegar in a jar with small iron objects (screws, bolts etc...) to produce rust (ferric oxide, right?). Once I made my rust vinegar, I paint with it. Are there any health risk associated with this? I.e. can the ferric oxide be absorbed by my skin and breathed in? I had a quick search, it appears that iron oxide is harmful when heated, but could not find any more info. Thank you
In order to determine if either of the materials, iron III oxide (Fe2O3) and vinegar, are reduced or oxidized when they react, we need to analyze the oxidation states of the elements involved.
Vinegar, which is primarily composed of acetic acid (CH3COOH), does not undergo oxidation or reduction during the reaction because carbon (C) in acetic acid maintains an oxidation state of +3, while hydrogen (H) holds an oxidation state of +1 and oxygen (O) retains an oxidation state of -2. Since no change occurs in the oxidation states of the elements in acetic acid, it is not oxidized or reduced.
Iron III oxide, on the other hand, contains iron (Fe) in its highest oxidation state (+3) and oxygen (O) with an oxidation state of -2. When it reacts with vinegar, which contains acetic acid, a chemical reaction occurs where iron III oxide is reduced to iron II ions (Fe2+) while vinegar is oxidized to carbon dioxide (CO2) and water (H2O).
To summarize:
- Iron III oxide (Fe2O3) is reduced because the iron ions change from an oxidation state of +3 to +2.
- Vinegar, specifically acetic acid (CH3COOH), is oxidized, resulting in the formation of carbon dioxide (CO2) and water (H2O).
It is important to note that during chemical reactions, elements can be oxidized or reduced based on changes in their oxidation states.
