Which one of the following is not a reducing power molecule?
Oxidation state of CinCO2 is +4, which is maximum So it does not undergo oxidation, and hence, it is not a reducing agent.
Which is the following oxidation reaction in corrosion?
In the case of corrosion, metal oxidation reaction (eqn [I]) is coupled with the reduction of species in the environment/electrolyte – the two most typical reactions taking place in aqueous environments are the reduction of protons (eqn [II]) or reduction of oxygen dissolved in water (eqn [III]).
Which of the following is an example of oxidation?
The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.
Why is rusted iron An example of an oxidation-reduction reaction?
Rusting of iron is an example of a redox reaction. During rusting, iron combines with oxygen in the presence of water. This is an oxidation reaction where oxygen acts as an oxidising agent. Since oxygen also combines with the metal iron, this is a reduction reaction, where the metal iron acts as a reducing agent.
Which species is acting as a reducing agent in the following reaction?
In the given reaction Ni acts as the reducing agent. It reduces dichromate ion. Hence, Ni is the reducing agent in the above redox reaction.
Is N2 O2 2no an oxidation-reduction reaction?
N2 is oxidizing with rise in oxidation state. O2 is reducing with decrease in oxidation state. Overall, N2 is reducing agent.
Which of the following is reduction?
The correct answer is option 3. Reduction means losing oxygen in a chemical reaction. In terms of electrons, the reduction occurs when an atom, molecule, or ion gaining one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species decreases.
What is oxidized and what is reduced in the following reaction 2 Al 3 Br2 → 2 AlBr3?
What is oxidized and what is reduced in the following reaction: 2Al + 3Br2 → 2 AlBr3? … Al is reduced and Br2 is oxidized.
Is CaO CO2 CaCO3 a redox reaction?
No, CaCO3 → CaO + CO2 is not a redox reactions.
Which of the following is not a reducing agent a sncl2 B Hi C NaNO3 D nano2?
Answer: Sodium nitrate NaNO3 is a strong oxidizing agent, it is not a reducing agent.
Which of the following is not reducing sugar?
Sucrose is a non-reducing sugar because the monosaccharides’ anomeric carbon is involved in glycoside or acetal formation.
Which of the following is not a reducing agent?
Co2 is not a reducing agent. To act as a reducing agent a compound should share or give electron and form another compound. But co2 has less electrons to from a bond.so it cannot reduce substances.
Which is not a reducing sugar?
As the reducing groups of the glucose molecule and fructose molecules are involved in the formation of the glycosidic, sucrose is considered a non-reducing sugar. Therefore, Sucrose is a non-reducing sugar.

Is corrosion reduction or oxidation?
Corrosion is a process through which metals in manufactured states return to their natural oxidation states. This process is a reduction-oxidation reaction in which the metal is being oxidized by its surroundings, often the oxygen in air.
Do metals go through oxidation or reduction?
Reduction is the gain of electrons and the gain of negative charge. Nonmetals are generally oxidized and become cations while metals are normally reduced and become anions.
Is rusting of iron an oxidation-reduction reaction?
Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.
What are some examples of oxidation-reduction reactions?
- 2NaH → 2Na + H. …
- 2H2O → 2H2 + O. …
- Na2CO3 → Na2O + CO.
What is one example of an oxidation-reduction reaction?
The tarnishing of silver is just one example of a broad class of oxidation-reduction reactions that fall under the general heading of corrosion. Another example is the series of reactions that occur when iron or steel rusts. When heated, iron reacts with oxygen to form a mixture of iron(II) and iron(III) oxides.
Is copper oxidized or reduced?
Copper(II) has an oxidation state of +2; the elemental metal has an oxidation state of 0. Gain of electrons is a reduction reaction. In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent. … Cu2+ ion gains two electrons (is reduced) to form copper metal.
Which species is the reducing agent?
The oxidizing agent is the species that’s being reduced, and the reducing agent is the species that’s being oxidized. Both the oxidizing and reducing agents are on the left (reactant) side of the redox equation.
Which species is the oxidizing agent in the reaction?
Common oxidizing agents | Common reducing agents |
---|---|
O2 | H2 |
O3 | CO |
F2 | Fe |
Br2 | Zn |
Is Zn a reducing agent?
The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. … The oxidizing agent is a substance that causes oxidation by accepting electrons. The reducing agent is a substance that causes reduction by losing electrons.
Is CH4 oxidized or reduced?
The most reduced form of carbon is CH4, the most oxidized is CO2.

Which of the following is reduction type of reaction?
Redox ( reduction – oxidation ) reactions are those in which the oxidation states of the reactants change. This occurs because in such reactions, electrons are always transferred between species.
Which one is a chemical reduction reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
