S+O2->SO2
Oxidation no. of sulphur changes from 0 to +4. Due to presence of d-orbitals(vacant) sulphur can extend its covalency & show oxidation states till +6, which is stable in sulphur (eg: SF6).
Hence it acts as a reducing agent.
Te+O2->TeO2
Oxidation no. of Te changes from 0 to +4. Unlike sulphur Te cannot show +6 oxidation state as it is highly unstable due to inert pair effect. Therefore there can only be a decrease in it oxidation state (it can decrease to -2, +2).
Hence it acts as an oxidising agent.

Is ammonium ion a reducing or oxidising agent?
Ammonium ion (NH4+) is a reducing agent because it can donate electrons to other species, causing them to be reduced. In this process, the ammonium ion itself becomes oxidized.
Is nitrogen an oxidizing agent or a reducing agent?
Nitrogen is neither an oxidizing agent nor a reducing agent in its elemental form. However, in some compounds like nitrogen dioxide (NO2), nitrogen can act as an oxidizing agent.
Is H2O2 a reducing agent?
Hydrogen peroxide (H2O2) can act as both an oxidizing and reducing agent, depending on the reaction conditions. In acidic conditions, it can act as a reducing agent, while in basic conditions, it tends to act as an oxidizing agent.
Is iron a stronger reducing agent than copper?
Yes, iron is a stronger reducing agent than copper. This is because iron has a greater ability to lose electrons and be oxidized compared to copper. Iron readily donates electrons to other substances, making it more effective at reducing them.
Is ethanol reducing agent?
Yes, ethanol can act as a reducing agent in certain chemical reactions. It can donate electrons to other molecules, causing a reduction reaction to occur.
Is hypo is an oxidising agent or reducing agent in photography?
Hypo is a reducing agent when combined with Na.
Is gold a reducing agent or a oxidising agent?
Gold is a reducing agent because it tends to lose electrons and undergo reduction reactions, in which it reduces other substances by donating electrons.
Is iodide an oxidising agent?
No iodide is a reducing (the opposite of oxidizing) agent at least with potassium iodide.
Which halogen is the strongest oxidising agent?
Fluorine is the strongest oxidising agent.
What is used to test for reducing and oxidising agents?
When some substances are oxidised or reduced, there is a colour change.Testing for a reducing agent:An oxidising agent is a substance that causes another substance to be oxidised & is itself reduced. Acidified potassium manganate (VII) is an example of one. While it oxidises other substances, the manganate ion is reduced (because the oxidation state decreases showing that reduction is occuring) :MnO4- --> Mn2+oxdations state:+VII+2colour:PinkColourlessSo, to see if an unknown substance is a reducing agent, add acidifies potassium manganate (VII) to see if the pink colour fades. If it does, you know the unknown substance was a reducing agent, because it caused reduction.Testing for an oxidising agent:A reducing agent is a substance which causes reduction, but is oxidised itself. Potassium iodide is a powerful reducing agent. While it reduces other substances, the iodide ion is oxidised (because the oxidising state increases) resulting in a colour change:2I- -->I2Oxidising state:-10 (the oxidising state of a diatomic molecule is 0)Colour:ColourlessRed-brownSo, to see if an unknown substance is an oxidising agent, add potassium iodide to see if a red-brown colour appears. If it does, you know your unknown substance is an oxidising agent because it caused a reduction

What is the oxidising agent in 3Mg plus N2 and rarrMg3N2?
Magnesium is the oxidising agent.
Sulphur dioxide can act as oxidising agent only?
Sulfur dioxide can act both as an oxidizing agent and a reducing agent. As an oxidizing agent, sulfur dioxide can be reduced to sulfur or sulfite ions. As a reducing agent, sulfur dioxide can be oxidized to sulfur trioxide or sulfuric acid.
Equation to show NO2 acts as a reducing agent and oxidising agent?
NO2(g)+SO2(g)-->NO(g)+SO3(g) here NO2 act as a oxidising agent
What is the relationship between oxidizing and oxidizing agent?
An oxidizing agent is a substance that causes another substance to be oxidized. Oxidation refers to the loss of electrons by a substance, while reduction refers to the gain of electrons. In a redox reaction, the oxidizing agent itself gets reduced as it accepts electrons from the substance being oxidized.
What is the Difference between an oxidizing agent and reducing agent?
An oxidizing agent is a substance that accepts electrons in a chemical reaction, causing another substance to be oxidized. A reducing agent is a substance that donates electrons in a chemical reaction, causing another substance to be reduced. In essence, an oxidizing agent promotes oxidation reactions, while a reducing agent promotes reduction reactions.
Is citric acid oxidising agent or reducing agent?
Citric acid is neither an oxidizing agent nor a reducing agent. It is a weak organic acid commonly found in citrus fruits and is used as a flavoring and preservative in various food and beverage products.
