What are the common strong oxidizing ions? What are the strong reducing ions?

Oxidizing agents: Fe3+, H+, Cu2+, Mno4-, ClO-, No3- (acidic), these are ions with significant oxidizing or reducing properties.

Common reducing ions.

fe2+,s2-,so3

2-,i-,br-,hs-(br-

Fe2+I-), oxidizing ions, F, flower lozenges, lambs, barley, cover, e3+, NO3-(H+), mNO4

2-,cl-,clo-,so4

2-,F-NO3-(H+) is very oxidizing because it is equivalent to the permanganate ion (purple) of nitrate is also very strong, and the acidic potassium permanganate is a strong oxidizing agent.

2-,F-NO3-(H+) is very oxidizing because it is equivalent to the permanganate ion (purple) of nitrate is also very strong, and the acidic potassium permanganate is a strong oxidizing agent.

Substances in the ** state are generally oxidizing, and some ** metals: Fe, MNO, etc.

Substances in the low-valence state are generally reducible (e.g., some metal elements (in middle school, metal elements are only reducible, in fact, negative valence metals are very common), some non-metal anions: br, i and so on.

Substances in the intermediate valence state are generally both reducing and oxidizing (e.g., tetravalent sulfur).

Ions that can be reflected: I-, Br-, S2-, SO3 2-, HSO3-, S2O3 2-, Fe2+, etc.

Ions that can be reflected: In addition to I-, Br-, S2-, SO3 2-, HSO3-, S2O3 2-, Fe2+, Cl-, etc.

Ions that can be reflected: In addition to I-, Br-, S2-, SO3 2-, HSO3-, S2O3 2-, Fe2+, Cl-, etc.

Among them, Cl-, Br-, and I- are oxidized to Cl2, Br2, I2SO3, 2-, HSO3-, S2O3, and 2- are oxidized to SO4, and 2-Fe2+ is oxidized to Fe3+, respectively

S2- is oxidized to elemental S or H2SO4

Mno4- (H+) is reduced to Mn2+

NO3- (H+) is reduced to NO or NO2 (concentrated nitric acid condition) and HCro is generally reduced to Cl-

Reaction principle: The oxidation of the oxidant is stronger than the oxidation of the oxidation product.

Give some points? Be more motivated!

1.Strong oxidizing ions: mNO4-, CR2O7 2-, NO3-, ClO3-, ClO-, ClO2-, IO3-, IO4-, BRO-, BRO3-, S2O8 2-, etc.

2.Strong reducing ions: S2-, I-, So32-, Fe2+, S2O32-, etc.

3.Strong oxidizing element: active non-metals, F2, O3, Cl2, Br2, O2 with strong electron acquisition ability

4.Strong reducible elemental: reactive metals or some non-metals with strong electron loss ability, Li, Na, K, Rb, CS, Ba, Sr, Ca, Mg, Be, Al, Zn and white phosphorus, activated carbon, H2 and so on.

2.Double-hydrolyzed ions:

SiO32- and NH4+, AlO2- and NH4+, Al3+, Fe3+, HCO3-, HSO3-, etc., CO32- and Fe3+, Al3+

1. The ions with oxidizing envy in high school chemistry include permanganate ions, hypochlorite ions, nitrate ions, iron ions, sulfate ions, etc.

2. The flammability of oxangelism refers to the ability of a substance to obtain electrons. Substances in the ** state generally have oxidative brother auspiciousness. Substances in a low-price state are generally reducible.

3. Judgment method: For metal reducing agents, the oxidation strength of metal cations is generally opposite to the order of metal activity, that is, the more metal in the back, the easier it is to obtain electrons, and the stronger the oxidation.

1. Oxidation of ions: refers to the ability of substances to obtain electrons, substances in the ** state and active non-metallic elementals, generally have oxidation, and substances in the low-valence state generally have reducibility;

2. The greater the concentration of oxidizing pants dust and substances, the stronger its oxidation, and vice versa;

3. When the variable valence element is in the most advanced state, it is only oxidized, when it is in the lowest valence state, it is only reductive, and when it is in the middle valence state, it has both oxidation and reduction;

4. Generally, when it is in the most advanced state, the oxidation is the strongest, and with the decrease of the valency, the oxidation is weakened and the reduction is enhanced.
