Strong oxidizing agent potassium permanganate, concentrated sulfuric acid, chlorine, oxygen, Fe+3, nitric acid...

Strong reducing agents: active metals, hydrogen, carbon,

Common oxidants are substances that are easily reduced in chemical reactions.

1) Typical non-metallic elements such as F2, O2, Cl2, Br2, I2, S, etc. (their oxidation is basically the same as that of non-metallic activity).

2) ** compounds containing valence elements, such as KMNO4, KCLO3, H2SO4, HNO3, Mno2, etc.

3) Metal cations such as: Fe3+, Cu2+, (H+) (in the displacement reaction of metal with acid and salt solution, such as the reaction Fe CuSO4=Feso4 Cu, it is essentially Cu2+ ions oxidizing Fe atoms, Cu2+ as oxidizing agent, and Fe as reducing agent).

A common reducing agent is a substance in which volatile electrons are oxidized in a chemical reaction.

1) Typical metal elements such as: K, Ca, Na, MG, etc. (their reducibility is basically the same as that of metal activity).

2) Certain non-metallic elements and their compounds, such as: H2, C, CO.

3) The lowest valence compounds with valence elements, such as: H2S, Hi, HBR, HCl

4) Non-metallic anions such as: S2-, I-, Br-, Cl-

Reducing agent: active metal elements, such as Na, Al, Zn, Fe, etc. Some non-metallic elements, such as H2, C, Si and other elements (such as C, S, etc.) are oxides when they are in low valency, such as Co, SO2 and other elements (such as Cl, S, etc.) Acids when they are in low valency, such as HCL, H2S and other elements (such as Fe, S, etc.) are salts when they are in low valency, such as Na2SO3, FeSO4, etc

Common reducing agents are:

Hydrogen (H2), carbon monoxide (CO), iron filings (Fe), zinc powder (ZN), etc.

Summary. Common reducing agents in high schools are: (1) metal elements: K, Na, MG, etc.; (2) Non-metallic elemental:

Such as trivalent cobalt salts, persulfates, peroxides, potassium dichromate, potassium permanganate, chlorate, concentrated sulfuric acid, etc. A reducing agent is a substance that loses or deviates from electrons in a redox reaction. The reducing agent itself is reducible and oxidized, and its products are called oxidation products.

The reduction and oxidation reactions are carried out at the same time, that is, the reducing agent is oxidized and becomes an oxide while oxidizing the reduced substance. The reactant with an elevated valency of a substance contained is a reducing agent.

In chemical reactions, reducing agents and oxidants are often used, so what are the commonly used reducing agents and oxidants in chemistry? Below I have compiled some relevant information for your reference!

1 Reducing agents and oxidants commonly used in chemistry1.Important oxidizing agent

In secondary school chemistry, there are generally the following types of important oxidants:

1) Active non-metallic elements, such as Cl2, Br2, O2, etc.

2) Oxides when elements (e.g., Mn, etc.) are in the valency of the high plexus, such as Mno2.

3) Oxygen-containing acids when elements (such as S, N, etc.) are in high valency, such as concentrated H2SO4, HNO3, etc.

4) Salts when elements (such as Mn, Cl, Fe, etc.) are in high valency, such as KMNO4, KCLO3, FeCl3, etc.

5) Peroxides, such as Na2O2, etc.

2.An important reducing agent

In secondary school chemistry, the important reducing agents are generally in the following categories:

1) Active metal elements, such as NA, AL, ZN, Fe, etc.

2) Some non-metallic elements, such as H2, C, Si, etc.

3) Oxides when elements (such as C, S, etc.) are in low valency, such as CO, SO2, etc.

4) Acids when elements (such as Cl, S, etc.) are in low valency, such as HCL, H2S, etc.

5) Salts when elements (such as S, Fe, etc.) are in low valency, such as Na2SO3, FeSO4, etc.

1 How to distinguish between oxidant and reducing agent Oxidant is a substance with oxidizing ability, such as O2, H2O2, etc., when oxidation occurs, the oxidant needs to get electrons to make its valence state low, such as O2 to O2-, from zero valence to -2 valence. Pure Zen.

On the contrary, when the reducing agent is oxidized, it loses electrons and its valence becomes high. For example, h2 changes from zero to +1.

Here Cl2 is both a reducing agent and an oxidizing agent, Cl2--- NaClCl is the oxidizing agent Cl2--- Naclocl is the reducing agent.

The main thing is to see which elements in the product have changed compared with the reactants, the valency has changed, the valency is oxidized, the valency is reduced, and then the elements that should be changed are from which reactants, the oxidized is the reducing agent, and the reduced is the oxidant.

As for the ratio of the quantity of matter, it can also be calculated from the change in the valency of the elements that produce the species, i.e., the gain and loss of electrons. The electrons gained by the oxidant are reduced, and the electrons lost by the reducing agent are oxidized. It is easy to calculate the ratio of the quantities of matter according to the balance of electrons gained and lost.

The common oxidants in high school chemistry are Cl2, Br2, O2, Mn, S, N, etc., and the common reducing agents are Na, Al, Zn, Fe, H2, C, Si, etc. Oxidizer is a substance with oxidizing ability, and when oxidation occurs, the oxidant needs to get electrons to make its valence state lower. When the reducing agent is oxidized, it loses electrons and its valence becomes high.

Strong oxidizing agent.

Active non-metallic elements, such as Cl2, Br2, O

Elements (such as Mn, etc.) are oxides when they are in high valency, such as MnO2 elements (such as S, N) strong reducing agents are salts at high valency, and active metal elements, such as Na, Al, Zn, Fe, and some non-metallic elements, such as H2, C, Si
