Chemistry / / July 04, 2021
BASIC OXIDES. They are formed when a metallic element and oxygen join, their chemical formulas are binary. The way his name is written is as follows:
RULE 1. First, the word oxide is written, which is its generic name.
RULE 2. Second, the name of the metallic element is written. Which carries the ending bear, if it acts with its lower oxidation number or carries the ending ico, if the element acts with its higher oxidation number.
EXAMPLE OF BASIC OXIDES:
Compound | Formula | Name |
Na+1+ O-2 | Na2OR | Sodium oxide |
Faith+2+ O-2 | Ugly | Ferrous oxide |
Neither+3+ O-2 | Neither2OR3 | Nickel oxide |
• ACID OXIDES (ANHYDRIDES). They are formed by the union between a non-metallic element and oxygen. His chemical formulas are binary and the way his name is written is as follows.
RULE 1. First, the word anhydride is written, which is its generic name.
RULE 2. Second, the name of the non-metallic element is written, with the endings bear or ¡co, depending on whether it acts with its lower or higher valence, respectively.
EXAMPLE OF ACID OXIDES:
Compound | Formula | Name |
S+4+ O-2 | SW2 | Sulphorous anhydride |
S+6+ O-2 | SW3 | Sulfuric anhydride |
P+3+ O-2 | P2OR3 | Phosphorous anhydride |
• HYDROXIDES OR BASES. They are formed when metallic oxides join with water, their chemical formulas are ternary and represent the union of a metallic element with the hydroxyl radical (OH-1). The way his name is written is as follows.
RULE 1. First, the word hydroxide is written, which is its generic name.
RULE 2. Second, the name of the metallic element is written, with the usual endings (bear for the minor, co for the major).
EXAMPLE OF HYDROXIDES:
Compound | Formula | Name |
K+1+ OH-1 | KOH | Potassium hydroxide |
Hg+2+ OH-1 | Hg (OH)2 | Mercuric hydroxide |
Co+3+ OH-1 | Co (OH)3 | Cobalt hydroxide |
• ACIDS. In these compounds its chemical formula always begins with hydrogen, chemically an acid is a substance that in aqueous solution can produce hydrogen ions (H +).
Depending on whether it contains oxygen or not, acids are divided into Hydracids and Oxyacids.
a) Hydracids. They are formed by the direct union, between hydrogen and a non-metallic element, of the groups Vla and Vlla, which when dissolved in water show their acid characteristics, with non-metallic elements of other groups, does not form compounds acidic. The way his name is written is as follows:
RULE 1. First, the word acid is written, which is its generic name.
RULE 2. Second, the name of the non-metallic element is written with the ending hydric.
EXAMPLE OF HYDRACIDS:
Compound | Formula | Name |
H+1+ Cl-1 | HCl | Hydrochloric acid |
H+1+ S-2 | H2S | Hydrogen sulfide |
H+1+ F-1 | HF | Hydrofluoric acid |
b) Oxyacids. They are formed when anhydrides join with water, their chemical formulas are ternary and represent the union of hydrogen with a negative radical, of which their name ends in ato and ito. The way his name is written is as follows:
RULE 1. First, the word acid is written, which is its generic name.
RULE 2. In second place, the name of the negative radical is written, changing the ending atho-ico and ito-bear.
EXAMPLE OF OXYACIDS:
Compound | Formula | Name |
H+1+ NO2-1 | HNO2 | Nitrous acid |
H+1+ NO3-1 | HNO3 | Nitric acid |
H+1+ SO3-2 | H2SW3 | Sulfurous acid |
• YOU GO OUT. These compounds are formed by neutralization between an acid and a hydroxide. As there are two varieties of acids, two different types of salts can be formed, if the salt comes from of a hydracid is called a haloid salt, but if the salt is generated from an oxyacid, it is called oxisal.
a) Haloidal salts. Their chemical formulas are generally binary and represent the union of a metallic element with a non-metallic element.
The way his name is spelled is as follows.
RULE 1 First, write the name of the non-metallic element, with the ending uro.
RULE 2. Second, the name of the metallic element is written, with the usual endings (bear - minor, ¡co - major)
EXAMPLE OF HALOID SALTS:
Compound | Formula | Name |
Na+1+ Cl-1 | NaCl | Sodium chloride |
Pt+2+ S-2 | PtS | Platinous sulfide |
Faith+3+ l-1 | Fel3 | Ferric iodide |
b) Oxisales. They are characterized because their chemical formulas are generally ternary and quaternary. Their formulas represent the union of a metal with a negative radical. The way his name is spelled is as follows.
RULE 1. First the name of the negative radical is written.
RULE 2. Second, the name of the metallic element is written, with the usual endings.
EXAMPLE OF OXYSALS:
Compound | Formula | Name |
K+1+ MnO4-1 | KMnO4 | Potassium permanganate |
Neither+2+ NO3-1 | Ni (NO3) 2 | Nickel nitrate |
Cr+3+ SO4-2 | Cr2(SW4)3 | Chromic sulfate |
