Question

Is $\mathrm{NaCl}$ it a mixture?

Answer 1

$\mathbf{NaCl}$ is not a mixture, it is a pure substance, ordinary table salt is sodium chloride with the chemical formula ($\mathbf{NaCl}$).

1. It is referred to as a substance because it has a consistent and definite structure.
2. Chemically, both samples of sodium chloride are identical.
3. Water is also a pure substance.
4. Aqueous sodium chloride is a homogeneous mixture because $\mathbf{NaCl}$completely dissolves in water, forming a distinctly visible phase.
5. In a solution, ${\mathbf{Na}}^{\mathbf{+}}$ , ${\mathbf{Cl}}^{\mathbf{-}}$ ions completely dissociate from each other and interact electrostatically with hydrogen and oxygen atoms in water.
6. Sodium chloride, also known as salt or $\mathbf{NaCl}$ is one of the most abundant minerals on Earth and an important source of nutrition for a variety of animals and plants. It occurs naturally in seawater and subsurface rock strata.

Pure Substance: The substance is composed entirely of one type or one type of atom is called an element, A substance is pure, it cannot be broken down or converted into another substance even by the use of physical or chemical methods. Mostly metals, or metalloids, non-metals form elements, When two or more elements are chemically combined in a specific ratio, pure substances are formed. However, chemical processes enable the breakdown of these compounds into their constituent parts.

Hence, $\mathbf{NaCl}$ is not a mixture.
