What chemicals does tin react with? Under what conditions is tin susceptible to oxidation?

Chemical properties. A protective film of tin dioxide is formed on the surface of the tin in the air and stabilized, and the oxidation reaction is carried out under heating.

Quicken; Tin reacts with halogen to form tin tetrahalide under heating; It can also react with sulfur; Tin is stable to water, can be slowly dissolved in dilute acid, and quickly dissolved in concentrated acid; Tin can be soluble in strong alkaline solutions; in ferric chloride.

Zinc chloride and other salts can be corroded by acidic solutions.

As the weather gets colder, we all wear thick clothes, but we all know that metal is very stable, but have you ever heard that metal is also afraid of cold?

Tin and common inorganic acids that do not have strong oxidizing properties can be replaced to release hydrogen. The effect of tin with inorganic acids is very slow, and it has almost no interaction with organic acids. However, organic acids in water and vegetables can react with tin to produce a very toxic tin methane, which can damage the central nervous system.

The chemical properties of tin are very stable. It does not react chemically with water, and even if it is exposed to moist air for a long time, it will only gradually form a dense oxide film on its surface, which prevents the further oxidation of tin.

Tin reacts with oxygen when heated to form tin dioxide. At high temperatures, tin reacts with chlorine to form tin tetrachloride (gas), which reacts with sulfur to form tin sulfide.

Tin does not react with water, reacts with hydrochloric acid, sulfuric acid, and dilute nitric acid to form stannous chloride, stannous sulfide and stannous nitrate, reacts with concentrated nitric acid to form tin dioxide, and reacts with concentrated sodium hydroxide solution to generate sodium stannitrate.

Tin is susceptible to oxidation under heated conditions.

Tin is malleable at room temperature. Especially at 100 °C, it is very malleable and can be rolled into extremely thin tin foil. Usually, people use tin foil to package cigarettes and candies to prevent moisture (in recent years, China has gradually replaced tin foil with aluminum foil.

Aluminium foil is easy to distinguish from tin foil – tin foil is much brighter than aluminium foil). However, the ductility of tin is very poor, and it breaks when it is pulled and cannot be drawn into filaments.

In fact, tin is only malleable at room temperature, and if the temperature drops below it, it will gradually turn into a loose powder like coal ash. In particular, in the presence of -33 or an alcohol solution with red salt (SNCL4·2NH4Cl), the rate of this change is greatly accelerated.

A well-ended tin pot will "automatically" turn into a pile of powder. This tin "disease" can also be transmitted to other "healthy" tin ware, which is known as the "tin plague". The cause of tin plague is due to a change in the crystal lattice of tin

At room temperature, tin is the crystal structure of a square crystal system, called white tin.

Tin Song Meng will oxidize.

Metal tin is stable by forming a tin dioxide protective film on the surface of tin in the air, and it is not easy to be oxidized at room temperature, and often maintains the shiny luster of silver, so it needs to be heated. When the tin is heated, the oxidation reaction will be accelerated and become tin dioxide.

Main Uses of Tin:

1. It is used as tin solder in the electronics industry, playing the role of mechanical connection, electrical connection and heat exchange.

2. It is used in the manufacture of tinplated sheets, such as tinplate as food and beverage packaging materials.

3. Tin compounds can be used as raw materials for enamel of ceramics, mordants for printing and dyeing silk fabrics, heat stabilizers for plastics, fungicides and insecticides.

Characteristics of tin: 1. Metal tin is soft, easy to bend, melting point, boiling point 2260 humming. There are three types of allotropes:

White tin is a tetragonal crystal system, unit cell parameters: a=, c=, the unit cell contains 4 sn atoms, the density is cubic centimeters, the hardness is 2, and the ductility is good;

Gray tin is a diamond-shaped cubic crystal system, unit cell parameters: a=, the unit cell contains 8 sn atoms, and the density is cubic centimeters;

Brittle tin is an orthorhombic crystal system with a density of cubic centimeters.

2. Tin is a silvery-white soft metal, with a specific gravity and a low melting point, only 232 years old in Yingzhou, put it into a briquette furnace, and it will melt into a mercury-like liquid.

3. The tin is very soft and can be cut with a knife.

4. Tin is non-toxic, and people often plate it on the inner wall of the copper pot to prevent copper and warm water from producing toxic patina (basic copper carbonate). <

Chemical properties. The tin dioxide protective film is formed on the surface of tin in the air and stabilized, and the oxidation reaction is accelerated under heating. Tin reacts with halogenidin under heating to form tetrahalide tin; It can also react with sulfur; Tin is stable to water, can be slowly dissolved in dilute acid, and quickly dissolved in concentrated acid; Tin can be dissolved in the alkaline solution of strong Jingchun; It will be corroded in salt-tolerant acidic solutions such as ferric chloride and zinc chloride.

1. In the air, the surface of tin is stabilized by the formation of tin dioxide protective film, and the oxidation reaction is accelerated under heating;

2. Tin and halogen react under heating conditions to form tin tetrahalide;

3. Tin can react with sulfur;

4. Tin is stable to water, can be slowly dissolved in dilute acid, and quickly dissolved in concentrated acid;

5. Tin can be dissolved in strong alkaline solution;

6. Tin will be corroded quickly in the acidic solution of salts such as ferric chloride and zinc chloride.

Tin is susceptible to oxidation under heated conditions.

Tin is an important common metal, which is inert, generally does not react with air and water, reacts slowly with dilute hydrochloric acid, and reacts with concentrated hydrochloric acid to form stannous chloride; It does not react with dilute sulfuric acid, and reacts with concentrated hot sulfuric acid to form denier tin sulfate; with concentrated hot nitric acid to form -stanic acid. It can be seen that the chemical properties of tin are relatively stable.

And because the metal tin rises on the surface of the tin in the air to form a tin dioxide protective film and is stable, it is not easy to be oxidized by mold disturbance under normal temperature conditions, and often maintains the shining luster of silver, so it needs to be heated. When the tin is heated, the oxidation reaction will be accelerated and become tin dioxide.

Summary. Hello, glad to answer for you. Tin is susceptible to oxidation under heated conditions and is not heat-resistant.

Under what conditions is tin susceptible to oxidation?

Hello, glad to answer for you. Tin is susceptible to oxidation under heated conditions and is not heat-resistant.

What solvent will oxidize with?

Tin foil can be oxidized at room temperature. However, it can still maintain the shiny surface of the tin foil for a long time. Mainly because it has a very thin oxide layer, which is characteristic of the metal tin.

Normal is how long it takes to be oxidized.

Looking at the temperature this way, the higher the temperature, the easier it is to oxidize.
