The chemical formula of Bordeaux liquid, the substance of Bordeaux liquid with Bordeaux chemistry

The chemical composition of the active ingredient of inorganic copper fungicide is CuSO4·XCU(OH)2·YCA(OH)2·ZH2O.

It is a sky blue gelatinous suspension formulated from about 500 grams of copper sulfate, 500 grams of hydrated lime and 50 kilograms of water. The ingredient ratio can be appropriately increased or decreased as needed.

The solution is a protective fungicide that inhibits spore germination or hyphae growth of pathogenic bacteria by releasing soluble copper ions. Under acidic conditions, when copper ions are released in large quantities, they can also coagulate the cell protoplasm of pathogenic bacteria and play a bactericidal role.

In the case of high relative humidity and dew or water film on the leaf surface, the efficacy is better, but it is easy to cause pesticide damage to plants with poor copper tolerance. It has a long effective period, and is widely used to prevent and control a variety of diseases such as vegetables, fruit trees, cotton, hemp, etc., and has a particularly good effect on downy mildew, anthracnose, potato late blight and other leaf diseases.

Hehe, amazing, can think.

Bordeaux liquid is an inorganic copper biocide.

The chemical composition of its active ingredient is CuSO4·XCU(OH)2·YCA(OH)2·ZH2O

This one is more complicated, so the book simplifies it, but it still has to be based on the textbook.

It's time to establish ionic consciousness, that matter doesn't exist in isolation.

CaSO4 and Cu(OH)2 can be seen as substances mixed together.

This doesn't need to be understood for the time being.

In short, respect textbook knowledge and follow textbooks.

Hope it helps.

1) 5 kinds of substances are common substances in junior high school chemistry, a and b are commonly used in agriculture to prepare pesticide Bordeaux liquid, and small chemical factories are commonly used to prepare caustic soda by the reaction of A and E, so A is calcium hydroxide, B is copper sulfate, E is sodium carbonate, C is the most common metal in life, D will react with calcium hydroxide and sodium carbonate, so D can be hydrochloric acid, C is iron, after verification, the derivation is correct, so the Liang Meng chemical formula of substance B is CuSO4

2) For metal C, the anti-rust measure is to keep the surface dry and clean;

3) The reaction between A and E is the reaction of sodium carbonate and hydroxide to produce calcium carbonate precipitate and sodium hydroxide, and the chemical equation is: Na2

The reaction between C and D is the reaction of iron and hydrochloric acid to produce ferrous chloride and hydrogen, and the chemical equation is: Fe+2HCl=FeCl2H2

So the answer is: (1) cuso4

2) Keep the surface dry and clean;

3）na2co3

caco3+2naoh，fe+2hcl=fecl2h2

The chemical formula of Bordeaux liquid is Fe4[Fe(CN)6]3.

Bordeaux liquid is a pesticide with good control effect, it is widely used in agricultural production, and has a good effect on the control of plant diseases and pests. Its main components are iron and cyanide. The chemical formula of Bordeaux liquid is Fe4[Fe(CN)6]3, and then we will learn more about the chemical formula of Bordeaux liquid and analyze its chemical structure and properties.

The chemical formula structure of Bordeaux liquid is complex, and its main components are complexes containing iron and cyanide ions.

Iron exists at +2 and +3 valences, and the chemical formula of the complex ion is [Fe(CN)6]3-The molecular formula of Bordeaux liquid is Fe4[Fe(CN)6]3, which can also be written as Fe8H2[Fe(CN)6]3·NH2O, where N is the number of water molecules. The chemical formula of Bordeaux liquid is a complex compound made up of many atoms and ions.

Bordeaux liquid is a colored precipitate with a pH. When the pH value is lower, the complex decomposes, producing toxic hydrogen cyanide gas.

The chemical formula structure of Bordeaux liquid is relatively complex, and it is a complex compound composed of a variety of protosheron and ions, and it needs to be used with caution because it contains cyanide ions. As a pesticide for the prevention and control of diseases, it plays a good role in agricultural production, and has been favored by many farmers. Because it contains cyanide ions, Bordeaux liquid needs to be stored and used properly to avoid contamination and harm to human health.

Application of Bordeaux liquid

Bordeaux slurry has a wide range of applications in agricultural production and performs well in plant disease resistance. It can effectively prevent and inhibit fungal and bacterial diseases of plants. Bordeaux liquid, as a pesticide for disease control, mainly plays a role in protecting crop foliage and fruits, and is simple and convenient to use, and is relatively cheap and widely used.

Bordeaux liquor is composed of several chemical components, including sulphate and lead copper, calcium hydroxide and water.

Bordeaux liquid is an inorganic copper biocide. The chemical composition of its active ingredient is CuSO4·XCU(OH)2·YCA(OH)2·yearFrench AMjalldai discovered its bactericidal effect in the city of Bordeaux, hence the name Bordeaux liquid.

It is a sky blue gelatinous suspension formulated from about 500 grams of copper sulfate, 500 grams of hydrated lime and 50 kilograms of water. The ingredient ratio can be appropriately increased or decreased as needed. It is generally alkaline and has good adhesion properties, but it is suitable to be used for a long time or made of dehydrated Bordeaux powder, and then mixed with water when used.

To prevent and control early apple defoliation, anthracnose and ring pattern disease, you can start to spray lime double Bordeaux liquid 200 240 times after the apple falls, spray once every half month, and alternately use it with other fungicides, a total of 3 4 times. To prevent and control apple rot disease (ring disease, anthracnose), you can spray lime multiplier or multi-amount Bordeaux liquid 200 times 10 15 days before the appearance of diseased fruit in previous years, spray 1 time every 15 20 days, spray 3 4 times, and stop using 25 days before fruit picking. To prevent and control apple mildew heart disease, 200 times of lime multiple-type Bordeaux solution should be sprayed at the beginning of the apple budding period.

To prevent and control apple fruit and pear rust, you can spray 160 times of lime equivalent Bordeaux liquid on the juniper cypress around the apple orchard. To prevent and control grape gangrene, anthracnose and downy mildew, a small amount of lime can be sprayed with 160 times of Bordeaux liquid, sprayed once every 12 15 days, a total of 2 4 times. After the rainy season, Bordeaux juice is used to control grape diseases.

1) a, b, c, d is a common substance in junior high school chemistry acid, alkali, salt, a is the highest annual output of a metal, so a is iron, c can be used to improve acidic soil, so c is calcium hydroxide, a and c reaction can be used to make bordeaux slag liquid, so a is copper sulfate, b will react with calcium hydroxide, iron, will be converted into copper sulfate, so b can be sulfuric acid, calcium hydroxide will be converted into d, d will react with copper sulfate, so d can make sodium hydroxide, b will be with sodium hydroxide, calcium hydroxide reaction, so B can be carbon dioxide, and the various substances that have been verified and launched meet the topic and are reasonably derived, so the chemical formula of A is Fe;

2) Through derivation, it can be seen that B is sulfuric acid, and sulfuric acid will react with metal oxides to remove rust on the surface of iron, so one of the uses of B is: metal rust removal;
