Salt – What are Salts, Usage and Formation

Grade 5
May 31, 2023

Introduction and Explanation:

Most of the acids and bases are found in nature on a regular basis, including citric acid in citrus fruits like oranges and lemons, tartaric acid in tamarind, malic acid in apples, and lactic acid in milk and milk products, and hydrochloric acid in gastric juices.

Similar to acids, several bases are present, including lime water. In our daily lives, we utilize several of these acids, like vinegar or acetic acid in the kitchen, boric acid for washing clothes, baking soda for cooking, washing soda for cleaning, etc.

A compound made of a metal and a nonmetal is usually called a salt.​ Salt is the typical name for a mixture of two elements, usually metals. By mixing sodium with chlorine, common table salt, also known as sodium chloride, is created. Salts are frequently A compound made of a metal and a nonmetal is usually called a salt. Salt is the typical name for a mixture of two elements, usually metals. By mixing sodium with chlorine, common table salt, also known as sodium chloride, is created. Salts are frequently created when the metals in the first two columns of the periodic table mix with the elements in the fluorine column.

An acid and a base can also be combined to create salt and water. The diagrams below illustrate both processes that produce salt.

Salt is the primary mineral component of seawater, which contains significant amounts of it. Animal existence depends on salt, and one of the fundamental human tastes is saltiness. The neutralization process between acids and bases produces salt, an ionic compound having a cation other than H+ and an anion other than OH, along with water

Acid base neutralization reaction

A salt’s particles form an organized arrangement due to their strong attraction to one another. Salts are usually brittle and hard. To separate them, a lot of heat energy is required. As a result, salts have high melting points: sodium chloride melts at 801 °C (1,474 °F), while sodium fluoride melts at
996 °C (1,825 °F).

Salt conducts electricity well when a metal and a nonmetal are dissolved together. In general, all salt solutions share this property. The electrical charge of the metal and nonmetal particles in salts is the cause. As shown in the diagram, these electrically charged particles can move through the water when salt dissolves. One method of conducting electricity is the movement of the charged metal and nonmetal particles.

Salt cannot produce a lot of freely moving charged particles if it does not dissolve efficiently in water. This salt solution won’t be an effective electrical conductor.

For example:

Barium sulfate salt is toxic. However, doctors make their patients drink barium sulfate suspensions because it dissolves so little in water. Barium sulfate sharpens X-ray images of the organs as it passes through a patient’s digestive system. The barium sulfate salt cannot be taken into the body due to its limited solubility.

Usage of Salts:

  1. Common Salt: Table salt is the most common type of salt and the one most used in home kitchens. Sourced from salt mines, it is then refined and most are minerals removed.

2. Washing Soda: Grease that has burned onto kitchen equipment can be removed with washing soda. It is widely utilized in the paper, glass, and soap industries.  Additionally, it aids in removing the water’s enduring hardness
