Why is chlorine a stronger oxidizing agent than oxygen?
A higher reduction potential means it's easier for the species to gain an electron (reduce), and Cl2 has a higher reduction potential than O2 (1.36 vs 1.23 V) so it's a stronger oxidizing agent. The reduction potential is directly coupled to the electronegativity. But it's the electronegativity of the Yes, chlorine's a stronger oxidizing agent.
Why is iodine not the strongest oxidizing agent?
On the other hand, Iodine is not the strongest oxidizing agent and does not make other species lose electrons very easily compared to the oxidizing potential of chlorine, bromine or fluorine. The other halogens are able to oxidize iodine anions as well but not vice versa.
What happens when you mix iodine and chlorine?
As you have seen above, chlorine can also oxidise iodide ions (in, for example, potassium iodide solution) to iodine: The iodine appears either as a red solution if you are mean with the amount of chlorine you use, or as a dark grey precipitate if the chlorine is in excess.
Why is chloride ion not an oxidizing agent?
Chloride ion will not gain further electrons to form Cl²⁻ or anything of that nature, so it cannot be further reduced. Therefore it is not an oxidizing agent at all.

Is iodine the best oxidising agent?
i) The halogens – oxidising agents Fluorine is the best oxidising agent, followed by chlorine. Iodine is a mild oxidising agent.
Is iodine a strong or weak oxidizing agent?
Iodine is a weaker oxidizing agent than bromine, chlorine, or fluorine.
Why is iodine stronger than chlorine?
Iodine is a larger molecule than chlorine, meaning it has more electrons. Therefore the London forces between neighbouring iodine molecules are stronger than those between neighbouring chlorine molecules.
Which is the strongest oxidising agent?
FluorineFluorine is the best oxidising agent, with the highest positive electrode potential value.
Is chlorine an oxidising agent?
Chlorine is a strong oxidizing agent. Its effectiveness depends on temperature, residual chlorine and reaction time. Before discharging ballast water it should be dechlorinated by using sulfur dioxide which reacts with residual chlorine to form chlorine ions [1].
Why iodide ions are stronger reducing agents than chloride ions?
Chlorine has the ability to take electrons from both bromide ions and iodide ions. Bromine and iodine can't get those electrons back from the chloride ions formed. That means that chlorine is a more powerful oxidising agent than either bromine or iodine. Similarly bromine is a more powerful oxidising agent than iodine.
Is iodine less reactive than chlorine?
Chlorine is more reactive than iodine.
Which is the strongest oxidising agent among halogens?
Florine is the most powerful oxidizing agent because it is the most electronegative element.
Is iodine a strong reducing agent?
Iodine has the highest electrode potential value and thus is the weakest oxidising agent or the strongest reducing agent.
Which is the weakest oxidizing agent?
Li+Li+ is the weakest oxidizing agent as it has most negative standard reduction potential.
Which of the following is a better oxidising agent?
`MnO_(4)^(-)` is strongest oxidising agent.
Which of the following is strongest oxidising and reducing agent?
Solution : Fluorine is the most electronegative element because electronegativity decreases on moving down the group. Hence, it gets reduced readily into `F^(+)` ion and is the strongest oxidising agent.
Why is chlorine happy to accept an eighth electron?
As it is a relatively small atom, with only seven electrons in its outer shell, it is happy to accept an eighth electron in order to achieve a stable noble gas electron arrangement. Because chlorine itself is reduced by extracting an electron from the compound that is oxidized. Fast. Simple.
What is the relationship between acid and oxidizing agent?
The experimental relationship between acids and oxidizing agents is a close one. In fact, as has been pointed out previously, the "typical" effect of an acid solution on metals is due to the oxidizing action of the solvent cation.
What is oxidizing agent hair?
An oxidising agent is a species that can be reduced (in order to oxidise another species) by accepting electrons from another atom.
What is an electrophilic reagent?
Electrodotic reagents are those which tend to lose electrons . (The word electrodotic is coined from the Greek word “Didomi”, meaning- “to give”) Some reagents may be electrophilic under one set of conditions while under another set of conditions the same reagents may be electrodotic.
Which has the highest electronegativity?
Fluorine has highest electronegativity and has more electron affinity and has small size than that of chlorine. Small size of fluorine affect its affinity,it acquires greater attraction for electron hence ,it is more oxidizing than chlorine. 4.5K views. ·. View upvotes.
How does hydrogen chloride behave in a reaction?
Even as strong - an acid as hydrogen chloride will behave as a base in the presence of a stronger acid such sulfur trioxide. The experimental r. Continue Reading.
Is chloride a weak reducing agent?
Continue Reading. It’s a very weak reducing agent. Consider that an oxidizing agent must be reduced (gain electrons) and a reducing agent must be oxidized (lose electrons). Chloride ion will not gain further electrons to form Cl²⁻ or anything of that nature, so it cannot be further reduced.
What is the reaction between iodide and chlorine?
In the chlorine and iodide ion case, the reaction would be: The iodide ions have lost electrons to form iodine molecules. They have been oxidised.
Which is more powerful, bromine or iodine?
Bromine and iodine can't get those electrons back from the chloride ions formed. That means that chlorine is a more powerful oxidising agent than either bromine or iodine. Similarly bromine is a more powerful oxidising agent than iodine.
Why is iodine red?
The iodine appears either as a red solution if you are mean with the amount of chlorine you use, or as a dark grey precipitate if the chlorine is in excess. Note: The reason for the red solution is that iodine dissolves in potassium iodide (or other soluble iodides) by reacting to give a red ion, I3-.
Why is fluorine low in bond enthalpy?
That is because the ion is very small. There is a very strong attraction between the fluoride ions and water molecules.
What is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mo
Electron affinity . The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous 1- ions. In symbol terms: Hydration enthalpy (hydration energy) This is the energy released when 1 mole of gaseous ions dissolves in water to produce hydrated ions.
Which halogens can oxidize the ions of one lower down?
Chlorine, bromine and iodine. In each case, a halogen higher in the Group can oxidise the ions of one lower down. For example, chlorine can oxidise the bromide ions (in, for example, potassium bromide solution) to bromine: The bromine appears as an orange solution. As you have seen above, chlorine can also oxidise iodide ions (in, for example, ...
Why are atoms less good at attracting new electrons and forming ions?
As the atoms get bigger, the new electrons find themselves further from the nucleus, and more and more screened from it by the inner electrons (offsetting the effect of the greater nuclear charge). The bigger atoms are therefore less good at attracting new electrons and forming ions.
