There are 5 electrons in
valence shell of N so it can
either gain 3(-3 oxidation
state) electron or at most
loose 5(+5 oxidation state)
electrons to gain the octet of
electron.In nitric acid
oxidation state of N is +5
which is maximum hence it
can gain the electrons only
and can be oxidizing agent.
while in nitrous acid oxidation
state of N is +3 so it can gain
or loose electron hence can be
oxidant or reductant both.

$SO_{2}$ can act as both oxidizing as well as reducing agent since it has +4 oxidation state which is exactly between its highest oxidation state +6 and lowest oxidation state +2 ,Thus it can change its oxidation number either from +4 to-2(reduction) and +4 to+6 (oxidation) .

Hope it will help u ....

Agents are just opposite

Explanation:

Oxidizing agent are those who add electropositive ions and remove electronegative ions but oxidizing is the reaction in which addition of electronegative ions and adding of electropositive ions.

Reducing agent are those who add electronegative ions and remove electropositive ions but Reduction is the reaction in which addition of electropositive ions and removal of electronegative ions.

Can PCl5 act as oxidising as well as reducing agent.Justify. PCl5 cannot act as reducing agent because it cannot increase its oxidation state beyond +5 and it can easily act as oxididsing agent because it can decrease its oxidation state from +5 to +3.

H2O2 can act as oxidizing as well as reducing agent in both acidic and basic media..e.g.,

(i) Oxidizing agent in acidic medium

2Fe²⁺(aq) + 2H⁺(aq) + H₂O₂ >2Fe³⁺(aq)+ 2H₂O(l)

(ii) Oxidizing agent in basic medium

Mn²⁺ (aq) + H₂O₂(aq)> Mn⁴⁺(aq) + 2OH⁻(aq)

(iii) Reducing agent in acidic medium

2MnO₄⁻(aq) + 6H⁺(aq) + 5H₂O₂(aq)> 2Mn²⁺ (aq) + 8H₂O(l) + 5O₂(g)

(iv) Reducing agent in basic medium

I₂(s) + H₂O₂(aq) + 2OH⁻(aq)> 2I⁻(aq) + 2H₂O(l) + O₂(g)

HEY MATE ^_^

=> In HNO3 , oxidizing state of nitrogen is +5.

The maximum and minimum oxidation state of nitrogen are +5 and -3 respectively.Thus there is only one possibility to decrease the oxidation state of nitrogen. In other words, HNO3 can be reduced only and hence acts as an oxidizing agent only.

=> In HNO2, oxidation state of nitrogen is +3. Thus oxidation state of nitrogen present in HNO2 can be increased or decreased and hence it can act as an oxidizing agent or as a reducing agent.

HNO3 acts as an oxidizing agent only whereas HNO2 acts an oxidizing as well as reducing agent. Why?
