What is the principle of aldehyde test for proteins?
formaldehyde reacts with oxidised indole ring to give coloured complex .mercuric sulphate in sulphuric acid acts as the oxidising agent
Why acid is added in KMnO4 titration?
as kmno4 acts as a strong reducing agent only in acid medium
Why SO2 acts as a reducing agent?
Because it may remove oxygen from a metal oxide and is converted into SO3.
What is the element which never acts as reducing agent?
Fluorine is probably the answer wanted, but helium and possibly neon also fit the characterization.
What happens to a reducing agent as it reduces?
In chemistry, reduction is defined as a phenomenon in which substance gets electron from other species, oxidation is defined as a process in which substance donates electron to other species. When a metal acts as reducing agent, the other substance (for which metal acts as reducing agent) gets electrons (from metal) and by definition goes on reduction, and the metal, in this process, donates electron so, metal itself undergoes to oxidation.
Why is sulfur-dioxide reducing while tellurium-dioxide is oxidising agent?
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.
What is the chemical equation to show that sulfur dioxide gas acts as a reducing agent?
2H2S(g) + SO2(g) --> 2H2O + 3S Fe2O3 catalyst and temperature 673K
What is the function of coke in a blast furnace?
Coke is used in furnaces as a reducing agent.
How can vitamin C function as an antioxidant?
Vitamin C acts as an antioxidant by reducing the concentration of oxygen. This is possible as it is a reducing agent.
Whenever ammonia donates an electron pair to form a covalent bond it acts as an?
Reducing agent

Is propane an oxidizing agent?
No it is not. Propane can be used as fuel during oxidation reaction however it is not an oxidizing agent. In a redox reaction such as combustion, propane acts as a reducing agent. Common agents are O2 and O3.

Is iron an oxidizing agent or reducing agent?
Zinc is a transition element with general oxidation state as +2. It gets easily oxidised to its oxidation state of +2 by elements which are less reactive than zinc . For example: 2Zn + H2O --> Zn2O + H2
