Salt (chemistry)
Salt (/sɔːlt/), in Chemistry, is a term that describes a class of chemical compounds that are formed from the reaction of an Acid with a Base. The term originates from the Latin word "sal", which means "salt".
Definition
In chemistry, a salt is a compound that is formed by the neutralization reaction of an acid and a base. Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge).
Properties
Salts can exhibit a large variation in their physical and chemical properties. Some salts are soluble in water, while others are not. Soluble salts, when dissolved in water, break apart into their constituent ions, a process known as Ionization.
Types of Salts
There are several types of salts, including:
- Normal Salts: These are formed when all the hydrogen ions of the acid are completely replaced by metal ions or ammonium ions.
- Acid Salts: These are formed when only a part of the hydrogen ions of the acid are replaced by metal ions or ammonium ions.
- Basic Salts: These are formed when a part of the hydroxyl ions of the base are replaced by acid radical ions.
- Double Salts: These are formed by the combination of two simple salts in the molecular proportion.
Uses
Salts have a wide range of uses, from food seasoning to industrial applications such as in the production of soap, glass, and paper.
