Q:What is the oxide: Elements and oxygen compounds are called oxides (and only two elements). Such as carbon dioxide (CO2), calcium oxide (CaO) Depending on the chemical nature of the oxide, the oxide according to whether the formation of salt with water and the type of salt can be divided into acidic oxides, alkaline oxides, amphoteric oxides and non-salt oxides [1] four categories. There are also many complex oxides.

Q:Acidic oxide is a kind of oxide which can form acid or react with water to form salt and water. Generally non-metallic elements of oxides and certain transition metal elements of high-priced oxide. Such as sulfur trioxide SO3, phosphorus pentoxide P2O5, manganese dioxide Mn2O7, chromium trioxide CrO3 and so on. Most of the non-metallic oxides are acidic oxides. In our familiar non-metallic oxides, carbon monoxide and nitric oxide are not acidic oxides, and are usually classified as non-acid oxides.: Acid oxide corresponding to the hydrate is acid, such as CO2 corresponding to the hydrate is H2CO3, N2O5 corresponding hydrate is HNO3.

Q:What is called transition metal oxide doping: Transition element refers to a series of metal elements in the d-region of the periodic table, also known as transition metal, including chromium, manganese, iron, cobalt, nickel, copper, zinc and so on are transition metals.

Q:Do not say fluorine gas, it is the strongest element, do not say that electronic anti-matter and current, authority ah: Oxygen is a colorless, almost odorless highly toxic gas, liquefied after the pale yellow. Because of the oxygen at room temperature with the dry air can react quickly to produce nitrogen dioxide and moldy colorless Gas nitrogen trifluoride (fluorine gas at room temperature with the dry air almost no reaction, which can be seen in the oxidation of tungsten fluoride), so usually see the fluoride is a brown odor of brown gas.

Q:Titanium oxide total of several?: Ti2O3 titanium dioxide purple powder, hexagonal crystal structure, lattice constant α = 0.5155nm. Containing oxygen 59.5% ~ 60.8% (at). Density 4.486g / cm3. Melting point 1900 ℃. Soluble in 40% Hydrofluoric acid, can be concentrated nitric acid erosion, but not concentrated hydrochloric acid, concentrated sulfuric acid erosion, nor for alkali erosion, and 30% (mass) hydrogen peroxide solution to produce a slightly yellow solution. ~ 300 ℃ into titanium pentoxide. Vacuum in 1600 ℃ heated titanium powder and titanium dioxide mixture or 1500 ℃ hydrogen reduction of titanium dioxide. Titanium ion itself is an excellent reducing agent.

Q:How to judge a chemical formula is not an oxide: Note that the most critical point is that all the oxygen elements must be -2 price, because there are some exceptions such as sodium peroxide, potassium oxide, but also by the two elements, one of which is the oxygen element, but the peroxide Sodium oxygen element is -1 price, the oxygen element of potassium oxide is -0.5. On the contrary which chemical formula is not an oxide at a glance

Q:What is salt oxide, what is not salt oxide?: No salt oxide no corresponding acid and acid roots such as: NO, CO, NO2

Q:Is SiO2 an amphoteric oxide?: Not though SiO2 reacts with HF but the reason for this reaction is not because H + is because Si and F-coordination generated SiF4 is very stable.

Q:What is the largest oxide of oxygen content?: [Oxygen content of the largest oxide] is hydrogen peroxide, the formula: H2O2; oxygen content of the mass fraction of 94.1%.

Q:Clothes on the metal buttons and metal ornaments for a long time there will be a layer of oxide, looks bleak, what good way to make these metal accessories smooth shiny?: Scrub with toothpaste, very effective oh ...
