The equation between hydrogen sulfide and sulfur, what is the equation for the reaction of hydrogen

The transformation between H2S and S is mainly due to these equations.

1) 2H2S + O2 (insufficient) == Ignition = = 2S ( ) 2H2O(2) H2 + S == == H2S (3) 2H2S + SO2 == 3S ( ) 2H2O (4) 2H2S + H2SO3 == 3S +3H2O(5) H2S + H2SO4 (concentrated) == S +SO2 + 2H2O(6) Cl2 + H2S (aqueous solution) == S +2HCl(7)BR2 + H2S (aqueous solution) == S +2HBR(8)I2 + H2S (aqueous solution) == S +2Hi(9)2Fe(3+) H2S (aqueous solution) == 2Fe(2+) S +2H(+)10)3H2S + 2Hno3 (dilute) == 3S +2O + 4H2O (H2S can also be oxidized by Hno3 to SO2 or even H2SO4) (*11) 3H2S + 2kmNO4 (rare, neutral condition) == 3S +2mNO2 +2KOH + 2H2O

Are you mistaken, it should be hydrogen sulfide and sulfur dioxide, you said that this reaction should not be high.

When there is excess acid in concentrated sulfur fiber stool: H2S + 3H2SO4 = 4SO2 + 4H2O When there is excess hydrogen before sulfur destruction and pin pin is rude: 3H2S + H2SO4 = = 4H2O + 3S When the concentration of hydrogen sulfide and concentrated sulfuric acid is about the same:

h2s+h2so4=s↓+so2↑+2h2o

It does not occur at the same time, but the amount of reaction that conforms to which one occurs.

The reaction between hydrogen sulfide (H2S) and concentrated sulfuric acid (H2SO4) produces sulfur dioxide (SO2) and water (H2O). The chemical equation for the reaction is as follows:

h2s + h2so4 so2 + 2h2o

This reaction describes the chemical change between hydrogen sulfide and concentrated sulfuric acid, in which hydrogen sulfide and sulfuric acid react to produce sulfur dioxide and water. Please note that this is only a simplified representation of the chemical equation, and the specific reaction conditions and reaction rates may be affected. In laboratory or industrial applications, specific temperatures, pressures, and reaction conditions may be required to induce the reaction to occur.

The chemical equation for the reaction of hydrogen sulfide with sulfur dioxide: 2H2S + SO2 = 2H2O + 3S.

Hydrogen sulfide and sulfur dioxide undergo a centering reaction, where hydrogen sulfide is the reducing agent, sulfur dioxide is the oxidizing agent, and sulfur is the oxidation product. Hydrogen sulfide is soluble in water.

Sulfur dioxide applications:

1. It is used as an organic solvent and refrigerant, and is used to refine various lubricating oils.

2. It is mainly used for the production of sulfur trioxide, sulfuric acid, sulfite, thiosulfate, and is also used as fumigant, preservative, disinfectant, reducing agent, etc.

3. Sulfur dioxide is a reductive bleach agent allowed to be used in China. It has a strong inhibitory effect on the bleaching of food and oxidase in plant food. China stipulates that it can be used for wine and fruit wine, and the maximum amount of use and residue shall not be exceeded.

Hydrogen sulfide is an inorganic compound with a molecular formula of H2S and a molecular weight, which is a flammable acid gas under standard conditions, colorless, smelling of rotten eggs at low concentrations, and sulfur smelling and highly toxic when the concentration is very low. The aqueous solution is hydrosulfuric acid, which is weaker acidic, weaker than carbonic acid, but stronger than boric acid. Soluble in water, soluble in alcohols, petroleum solvents and **.

Hydrogen sulfide is a flammable and hazardous chemical, which can be mixed with air to form a first-class mixture, which can cause combustion in case of open flame and high heat energy. Hydrogen sulfide is an important chemical raw material.

Hydrogen sulfide gas is soluble in water, ethanol and glycerin, and is chemically unstable. Slightly soluble in water, it forms a weak acid, called "hydrosulfuric acid". The aqueous solution contains hydrosulfate Hs-(in a molloliter solution at 18 degrees Celsius, pka = and sulfur ion S2-.

At first, the clear hydrosulfuric acid will become cloudy after a period of time, because the hydrosulfuric acid will react slowly with the oxygen dissolved in the water to produce elemental sulfur that is insoluble in water.

Hydrogen sulfide is a dibasic weak acid. At 20 hours1 volume of water can dissolve the volume of hydrogen sulfide, the resulting aqueous solution is called hydrosulfuric acid, the concentration of hydrogen sulfide in the second stage of ionization in water is quite low, so that the concentration of hydroxide at least 8mol l sulfur ions can be detected by the instrument.

Because elemental sulfur has six electrons in the outermost shell, and the number of electron layers is three, it has relatively strong oxidation, while hydrogen has relatively strong reducibility, so sulfur is burned in hydrogen, sulfur is reduced to sulfur ions, and hydrogen is oxidized to hydrogen ions, so the final product is hydrogen sulfide.

s ten h2 = h2s ignition.

Hydrogen sulfide + chlorine.

h2s+cl2=2hcl+s↓

Hydrogen sulfide + oxygen.

2H2S + 3O2 = Ignition = 2H2O + 2SO2 Hydrogen Sulfide + Sulfur Dioxide.

2h2s+so2=3s↓+2h2o

Hydrogen sulfide + dilute hydrochloric acid, hydrogen sulfide + concentrated hydrochloric acid (does not seem to react, because the hydrogen sulfide preparation method is as follows: Fes + 2HCl = FeCl2 + H2S).

Hydrogen sulfide + dilute nitric acid.

2HNO3 + 3H2S ===3S +2NO +4H2O hydrogen sulfide + concentrated nitric acid.

H2S + 2Hno3 ===S +2NO2 + 2H2O hydrogen sulfide + iron chloride.

H2S+2FeCl3=2FeCl2+S +2HCL Hope it helps.

Molecular formula: H2S

Laboratory method: Fes+H2SO4 (dilute)=FeSo4+H2S After contact with hydrogen sulfide and silver, black-brown silver sulfide will be produced

H2S + 2AG AG2S + H2 Combustion (decomposition) product: sulfur dioxide.

Chemical equation: 2H2S + 3O2 = = 2H2O + 2SO2 (O2 excess) 2H2S + O2 = = 2H2O + 2S (O2 insufficient).

When there is an excess of concentrated sulfuric acid: H2S + 3H2SO4 = 4SO2 + 4H2O When there is an excess of hydrogen sulfide: DU3H2S + H2SO4 = = 4H2O + 3S When the amount of hydrogen sulfide and concentrated sulfuric acid is the same:

h2s+h2so4=s↓+so2↑+2h2o

Concentrated sulfuric acid is highly corrosive: at atmospheric pressure, boiling concentrated sulfuric acid can corrode all metals except iridium and ruthenium (even gold and platinum), and the number of elemental metal species that can be corroded even exceeds that of aqua regia. Sulfuric acid has strong oxidizing properties at high concentrations, which is one of the biggest differences it has from dilute sulfuric acid.

At the same time, it also has dehydration, difficult volatility, acidity, water absorption, etc.

Four sulfur elements in excess of hydrogen sulfide.

The chemical formula of the reaction is FeSO4+Na2S=Fes+Na2SO4 Reaction phenomenon: there is a black precipitate and the yield loss of Lusensheng.

The resulting product is non-toxic.

Metal sulfides are the form of sulfide resistance (metal). Metal sulfides can be formed from the formation of binary compounds from sulfur and metals, or from the reaction of hydrogen sulfide (or hydrosulfuric acid) with metal oxides or hydroxides.

Water solubility of metal sulfides: sodium sulfide, potassium sulfide, etc. are easily soluble in water, and other sulfides are completely insoluble in water.

Acid solubility of metal sulfides: sodium sulfide, potassium sulfide, zinc sulfide, magnesium sulfide, ferrous sulfide, manganese sulfide, etc. are soluble in dilute acid, and other lead sulfide, cadmium sulfide, antimony sulfide, stannous sulfide, silver sulfide, copper sulfide, mercury sulfide are insoluble in dilute acid. That is, alkali metal sulfides are soluble, and alkaline earth metal sulfides, such as calcium sulfide, strontium sulfide, barium sulfide, etc., are slightly soluble in water.

The reaction between sulfuric acid and hydrogen sulfide can be expressed as the following chemical equation:

h2s + h2so4 ->s + 2h2o

Among them, H2S represents hydrogen sulfide, H2SO4 represents sulfuric acid, S represents elemental sulfur, and H2O represents water. This square combustion formula indicates that hydrogen sulfide and sulfuric acid should be repented to produce sulfur and water.
