30 Examples of Binary Sales

The binary salts (neutral salts) are formed when a metal and a non-metal combine. Are chemical compounds made up of only two chemical elements. For example: sodium chloride (NaCl) and potassium bromide (KBr).

Nomenclature of binary salts

According to Traditional Nomenclature, binary salts are named by writing the name of the non-metallic element with the ending -ide. On the other hand, the name of the metallic element is written according to its oxidation state:

• For the lowest oxidation state, it is written with the ending -oso. For example: ferrous chloride (FeCl₂), where iron has an oxidation state of 2+.
• For the highest oxidation state, it is written with the ending -ico. For example: ferric chloride (FeCl₃), where iron has an oxidation state of 3+.

According to Systematic Nomenclature, binary salts are named by writing the name of the non-metallic element with a prefix that indicates the amount of atoms of this element in the compound. In addition, the ending -uro is placed in the name of the non-metallic element. Then, the name of the metallic element is placed. For example: magnesium dichloride (MgCl₂) and iron trichloride (FeCl₃).

According to Stock's nomenclature, binary salts are named by writing the name of the nonmetallic element with the ending -ide. Then, the name of the metallic element is placed followed by its oxidation state written in Roman numerals and in parentheses. For example: iron(II) chloride (FeCl₂) and cobalt(III) sulfide (Co₂Yes₃).

Applications of binary salts

• They are used as refrigerants in the food and pharmaceutical industries. For example: calcium chloride (CaCl₂).
• They are used to treat metal surfaces against corrosion. For example: sodium fluoride (NaF).
• They are used to regulate humidity in the paper and construction industry. For example: calcium chloride (CaCl₂).
• They are used in the glass industry to eliminate impurities. For example: silicon tetrachloride (SiCl4).
• They are used as cooking ingredients. For example: sodium chloride (NaCl).

Physical properties of binary salts

• They have high melting points because they are made up of ionic bonds.
• They conduct electric current when dissolved or molten.
• The most common salts have low hardness.
• They are not compressible.
• Most can dissolve in water.

How are binary salts obtained?

Binary salts can be obtained through some of the following chemical reactions:

Reaction between a metal and a non-metal. For example: the reaction between sodium (Na) and dichloride (Cl₂) produces sodium chloride (NaCl).

Reaction between a metal and an acid. For example: The reaction between potassium (K) and hydrochloric acid (HCl) produces potassium chloride (KCl) and dihydrogen (H₂).

Reaction between an acid and a base. For example: The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) produces sodium chloride (NaCl) and water (H₂EITHER).
