Inorganic Compound Role

Inorganic compounds, compounds has nothing to do with the body (a few related to the body of the compound and inorganic compound, such as water), and organic compounds, usually refers to do not contain carbon compounds, including carbon oxide, carbonate, carbonate, cyanide, etc., hereinafter referred to as inorganic substances.

The vast majority of inorganic materials can be classified into four categories: oxide, acid, alkali and salt. The inorganic substances in the organism mainly include water and some inorganic ions such as Na +, K +, Ca2 +, Mg2 +, Cl -, SO42 -, etc. Almost contains all the elements in nature exist in the human body tissues, which in addition to carbon, hydrogen, oxygen and nitrogen mainly exists in the form of organic compounds, the rest are collectively referred to as inorganic minerals (or ash). So, mineral mainly consists of: water and inorganic salt, the water can be classified as: bound water and free water and bound water is important components of cellular structure, free water is a good solvent, transport material, participate in chemical reactions. And compounds, inorganic salt can be divided into: ions cells is to maintain normal life activities, compound is an important component part of intracellular compound oxide is made up of two elements, one of the elements is a compound of oxygen. The substance that can react with oxygen is called an oxide. According to the chemical properties, the oxide can be divided into acidic oxide and alkaline oxide. Acid oxide: an oxide that ACTS as an acid or salts with water. For example, sulfur trioxide, phosphorus oxide, carbon dioxide, etc., most of which are acidic oxides.

Alkaline oxides: oxides that can react with acids to form salts and water, and products can only have salt and water, and no other substances can be produced. Basic oxides include active metal oxide and other metals with low - price oxides such as CaO, BaO, and CrO, MnO.

Inorganic acid

A group of compounds that can ionize and produce H in an aqueous solution. Ionization in hydrochloric acid, sulfuric acid, nitric acid in aqueous solution, the anion (the acid radical) is different, but the cation (H) is the same, so they have a common place in nature, such as acidity; It can dissolve a lot of metal; Can make blue litmus test paper turn red and so on. A narrow definition: ionized cations in aqueous solutions are all compounds of hydrogen ions (such as sulfuric acid). Most of these substances are soluble in water, and a few, such as silicic acid, are difficult to dissolve in water. The aqueous solution of acid is generally conductive, and some acids exist in the form of molecules in the water and do not conduct electricity. Partial acid is dissociating into positive and negative ions in water, which can conduct electricity.

More broadly defined: the reaction can provide protons with acids that define acids as the recipients of electronic pairs, and the range is broader. Acids neutralize the base, producing water and salt.


A substance that tastes bitter and can change the color of a specific indicator (such as turning the litmus blue, making the phenolphthalein red, etc.), and the PH value is greater than 7. All ions ionized in aqueous solutions are hydroxide ions, which react with acids to form salts and water. Typical alkaloids such as amine (including ammonia), caustic soda (sodium hydroxide), and hydrated lime (calcium hydroxide). The more general concept of a base is the material that provides the electron, or the substance that accepts the proton


The product of acid and base neutralization is composed of metal ions (including ammonium ion) and acid-root ions. There are three kinds of salt in chemistry: the salt is the salt: the single metal ions (including ammonium ion) and non-metal ions. Acid salt: composed of metal ions (including ammonium ions), hydrogen ions and nonmetallic ions; Basic salt: composed of metal ions (including ammonium ion), hydroxide anions and nonmetallic ions. Salt is an important source of chemical industry, which can be made into chlorine gas, sodium metal sodium, soda ash, heavy alkali (sodium bicarbonate, baking soda), caustic soda (caustic sodium hydroxide) and hydrochloric acid.
