How does chlorine act as an oxidising agent?
Chlorine has the ability to take electrons from both bromide ions and iodide ions. Bromine and iodine cannot reclaim those electrons from the chloride ions formed. This indicates that chlorine is a more powerful oxidizing agent than either bromine or iodine.
Why ce4+ is a oxidising agent?
Why is Ce4+ in aqueous solution is good oxidising agent. Electronic configuration of Cerium is 4f1 5d1 6s2 , the most stable state of cerium is +3. Thus, Ce4+ is good oxidising agent because it can readily chagne to the most stable +3 oxidation state by gaining one electron.
Why pbcl2 is a good oxidizing agent?
In PbCl2, there is Pb2+ ion. It can still loose two more electron to have +4 oxidation state. It loses electrons that’s why act as oxidising reagent.
Why is teo3 an oxidising agent?
Te is a heavy element and so because of the inert pair effect, the lower oxidation state is more stable. Hence, it acts as an oxidising agent.
Why are halogens strong oxidising agents?
Also, halogens are highly electronegative with low dissociation energies and high negative electron gain enthalpies. Therefore, they have a high tendency to gain an electron. Hence, they act as strong oxidizing agents.
Why does Ce4+ behave as good oxidising agent although as a stable species?
The formation of Ce4+ is favoured by its noble gas configuration, but it is a strong oxidant reverting to the common +3 state because the Eo value for Ce4+/ Ce3+ is + 1.74 V which is positive.
Why Ce4 is a good analytical reagent?
An analytical reagent is considered good if it has a high standard for purity. The cerium (IV) has sufficient kinetic stability due to the reaction rate being very slow and hence cerium (IV) is a good analytical reagent.
Why PbCl2 is stable than PbCl4?
➡️Pb has 2 electrons in s orbital while 2 electrons in p orbital . So s electrons are inert and can not be removed and give valency of 4. Hence Pb forms 2 ions instead of 4 and PbCl2 becomes stable. ➡️Moreover , due to inert pair effect, higher oxidation state of an element is not stable as we move down the group.
Why PbCl2 is more stable and PbCl4?
due to inert pair effect Pb show it’s valency as +2 so PbCl2 is more stable.
Why does SO2 show oxidizing and reducing agent?
Why SO2 can act as oxidising as well as reducing agent but H2S act as only reducing agent. In SO2, S is in oxidation state with +4 charge and the highest oxidation state is +6. So, it acts as both oxidising as well as reducing agent. Therefore, it acts only as a reducing agent.
Why SO2 is reducing agent and oxidizing agent?
i) Sulphur dioxide is reducing agent because sulphur has d-orbital so it can easily expand its oxidation state +4 to +6 and thus behave as reducing agent. Nitrogen does not have d orbital and due to the absence of d -orbital it does not form pentahalide.
What is the name of the compound with the formula SnCl4?
Tin (IV) chloride From Wikipedia, the free encyclopedia Tin (IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound with the formula Sn Cl 4. It is a colorless hygroscopic liquid, which fumes on contact with air.
What is stannic chloride used for in organic chemistry?
Stannic chloride is used in chemical reactions with fuming (90\%) nitric acid for the selective nitration of activated aromatic rings in the presence of inactivated ones. The main application of SnCl 4 is as a precursor to organotin compounds, which are used as catalysts and polymer stabilizers.
Why does stannous chloride give grey precipitate with mercuric chloride?
Assertion: Stannous chloride gives grey precipitate with mercuric chloride, but stannic chloride does not do so. Reason: Stannous chloride is a powerful oxidising agent which oxidises mercuric chloride to metallic mercury Please log in or register to add a comment.
What is the oxidation state of tin in SnCl4?
In SnCl4, the oxidation state of Tin is +4. Tin is also capable of forming stable compounds and ions with the oxidation state of +2, due to inert pair effect that is, it is capable of gaining 2 electrons from some other source.
