What are the red solids? What kind of chemical is a reddish brown solid?

The color of the solid.

1. Red solid: copper, iron oxide, mercury oxide.

2. Green solid: basic copper carbonate.

3. Blue solid: copper hydroxide, copper sulfate crystals.

4. Purple-black solid: potassium permanganate.

5. Light yellow solid: sulfur.

6. Colorless solids: ice, dry ice, diamond.

7. Silver-white solid: silver, iron, magnesium, aluminum, mercury and other metals.

8. Black solid: iron powder, charcoal, copper oxide, manganese dioxide, ferric tetroxide, (carbon black, activated carbon).

9. Reddish-brown solid: iron hydroxide.

10. White solid: sodium chloride, sodium carbonate, sodium hydroxide, calcium hydroxide, calcium carbonate, calcium oxide, copper sulfate, phosphorus pentoxide, magnesium oxide.

The reddish-brown solids in junior high school chemicals include iron oxide, red phosphorus (red phosphorus), iron hydroxide, lead oxide, vanadium pentoxide, and cuprous oxide.

1. Iron oxide.

Iron oxide is easily soluble in strong acids, medium strong acids, and has a reddish-brown appearance as a powder. Its reddish-brown powder is a low-grade pigment, known as iron oxide red in industry, used in paint, ink, rubber and other industries, can be used as a catalyst, glass, gemstones, metal polishing agent, can be used as ironmaking raw materials.

2. Red phosphorus. Red phosphorus is a purplish-red or slightly brownish amorphous powder with a shiny finish. It can be melted when heated to 590 degrees at a pressure of 4300kpa. After vaporization, white phosphorus is obtained by condensation.

Insoluble in water and CS2, ether, ammonia, etc., slightly soluble in anhydrous ethanol, non-toxic and odorless, white smoke is produced when burning, and the smoke is toxic.

3. Iron hydroxide.

Iron hydroxide is a brown or reddish-brown powder or dark brown flocculent precipitate or colloid. Iron hydroxide can be used to make pigments, medicines, water purification agents (colloidal), and can also be used as an antidote to arsenic.

4. Vanadium pentoxide.

Vanadium is a non-ferrous metal, vanadium pentoxide is widely used in metallurgy, chemical and other industries, mainly used for smelting ferrovanadium as an alloy additive, accounting for more than 80% of the total consumption of vanadium pentoxide, followed by being used as a catalyst for organic chemicals, that is, a catalyst, accounting for about 10% of the total.

5. Cuprous oxide.

Cuprous oxide is a yellow to red crystalline powder. The difference in color is caused by the size of the particles. The structure is a cuprite-type structure (cubic crystal system) with relative density.

The melting point is 232, and the heat of generation is. In 1800 it loses oxygen, is insoluble in water and dissolves in ammonia, and reacts with concentrated hydrochloric acid to produce a white cuprous chloride crystalline powder.

Copper, red phosphorus and other red solid elements, as well as related compounds such as iron oxide, which we learn about ferric oxide is reddish-brown, and iron chloride, iron sulfate, ferric nitrate, and iron hydroxide are all red solids. It's all something we can easily learn about in junior high school chemistry.

And in the Divine Burning Chain textbook, we learn:1Ferric oxide is a kind of substance that can be dissolved in strong acids with a reddish-brown appearance and a powdery state, which can be used in the rubber industry, plastic industry, paint and coating components, etc., and can also be used in ironmaking and other industrial tourism to play a catalytic role.

2.Red phosphorus is a purple-red and non-toxic powder substance with metallic luster, and its chemical properties are insoluble in water and organic solutions such as ethanol.

3.Copper: It is also a solid that is red at room temperature, with a metallic luster on the surface, and its good ductility and thermal conductivity make it one of the most common materials for cable processing clocks in the electrical segment key gas industry. as well as Cu2O for brick red and so on.

The substance of the red solid is as follows:

1. Iron hydroxide: brown or reddish-brown powder or dark brown flocculent precipitate or colloid, which is used to make pigment and dark brown excitation, medicine, water purification agent, and arsenic antidote.

2. Red phosphorus is a purple-red or slightly brown amorphous powder with a shiny color.

3. Cuprous oxide, which is an oxide of monovalent copper, is a dark red or dark brown crystalline powder. It is easy to oxidize in humid air, soluble in acid free grip and concentrated ammonia, insoluble in water, 4. Metal copper, pure copper is light rose or light red, and the appearance is purple stove socks copper after the formation of oxide film on the surface.
