Iron has been oxidised (by an oxidant) due to its loss of 2 or 3 electrons:
- Fe --> Fe2+ + 2e- , or Fe --> Fe3+ + 3e-
The oxidant picked them up.
(Examples of oxidants:
- 2H+ + 2e- --> H2
- 4 H2O + O2 + 4e- --> 4 OH-

Is a rusting car a redox reaction?
Yes, rusting is oxidation of iron. The iron is oxidised, the oxygen is reduced. This is thus basically a redox reaction.
How does cast iron react to salt water?
It corrodes badly.
What is oxidized in H2 Cl2?
in the reaction of H2 and Cl2 hydrogen is oxidised. Chlorine is reduced.
How does NAD plus get oxidized?
NAD+ isn't oxidised, it can be reduced by H to form NADH
What is the most common magnetic element that corrodes to form rust?
The most common magnetic element that corrodes to form rust is iron. When aligned, atoms of iron will possess a magnetic field that will lead to interaction with other magnetic, ferrous materials. Iron will oxidize to form rust.
Is a rusting car a redox reaction?
Yes, rusting is oxidation of iron. The iron is oxidised, the oxygen is reduced. This is thus basically a redox reaction.
What substance in blood reacted with hydrogen peroxide?
The iron in haemoglobin is reduced oxidised by the hydrogen peroxide which is an oxidising agent.
Is the element zinc easily reduced?
No it is not. However, it is easily oxidised.
What is it called when an element is simultaneously oxidised and reduced in a reaction?
disproportionation
Why are many things that are made of iron disposable?
because iron corrodes and its cheap
Which metal become brown in colour when it is oxidised?
Iron.
When Iron corrodes in the presence of air and water to form what?
IRON OXIDE.......AKA RUST!
Is iron oxide ruduced or oxidised in a blast furnace?
It is 96% iron (the rest is mostly sulphur etc.).
How does cast iron react to salt water?
It corrodes badly.
What metal corrodes easily to form rusty oxide?
This metal is iron.
Why sulfuric acid is added in preparing FAS Solution?
Adding acid is "belt and braces" - iron II is readily oxidised to iron III but this is greatly reduced in the prescence of the ammonium ion which is slightly acidic. Adding more acid merely futher reduces the tendancy for oxidation of the iron II.
What is oxidized in H2 Cl2?
in the reaction of H2 and Cl2 hydrogen is oxidised. Chlorine is reduced.
