Which is stronger oxidising agent CO2 or PbO2?
As Oxidising agent oxidises other species and itself undergoes reduction therefore, Pb in PbO2 (i.e. +4 Oxidation state ) acts as a strong oxidising agent. …
Is PbO2 is oxidising agent?
Pb has an oxidation state of +4 in PbO2, but Pb+2 is more stable, due to which pb+4 has an innate ability to get converted into Pb+2, thus being able to oxidise others in the reaction. …
Is CO2 a good oxidizing agent?
The abundant availability, non-toxic, economic and mild oxidizing properties of CO2 has resulted in immense interest in its use as an oxidant in several reactions, such as the oxidative coupling of CH4 and the oxidative dehydrogenation of alkanes and alkyl aromatics.
Which oxide is strongest oxidizing agent?
The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element.
Why is PbO2 stronger oxidising agent?
In PbO2 and SnO2, both lead and tin are present in +4-oxidation state. But due to stronger inert pair effect, Pb2+ ions is more stable than Sn2+ ions . Thus, PbO2 acts a stronger oxidising agent than SnO2.
Why PbO2 is a stronger oxidising agent than SnO2?
In p block elements, the last element of the group show inert pair effect. In inert pair effect the inner ns orbital of valence electrons do not take part in hybridization and become inert. PbO2 has +4 oxidation state so it gains two electrons and become PbO in +2 oxidation state and reduces itself and oxidises other.
Which is more stable PbO2 or PbO?
PbO is much more stable than PbO2 due to inert pair effect. This is the reason, PbO2 decomposes readily to PbO to attain stability.
Is CO2 reduced or oxidized?
Water is oxidized in photosynthesis, which means it loses electrons, and carbon dioxide is reduced, meaning it gains electrons.
What is the weakest oxidizing agent?
H2O2 H 2 O 2 is a weakest oxidising agent because it can act as a reducing agent also.
Which is the most strongest oxidizing agent?
The most powerful oxidising agent is Flourine. It has the highest positive electrode potential value. Due to high electronegativity and high electron affinity, halogens act as a strong oxidising agent, enabling them to take electrons very quickly and easily from other elements and oxidise other elements.
Which is the weakest oxidizing agent?
Oxygen, hydrogen peroxide and halogens are the common oxidizing agents. etc are the examples of weakest oxidizing agents.
Which is better oxidising agent PbO2 or SnO2?
In Sn +4 oxidation state is more stable than +2 oxidation state. But in case of Pb due to inert pair effect +2 oxidation state is more stable and so Pb+4 gets converted into Pb+2 easily and acts as a good oxidizing agent.
