Question

One of the natural minerals of sodium is tincal. Its formula is
A. $N{{a}_{2}}C{{O}_{3}}.10{{H}_{2}}O$
B. $NaN{{O}_{3}}$
C. $N{{a}_{2}}{{B}_{4}}{{O}_{7}}.10{{H}_{2}}O$
D. $NaCl$

Answer 1

We know that the naturally occurring substance that has a definite chemical composition is a mineral. They are created by natural processes without any human interference. They can be identified based on their physical properties such as color, density, hardness, and chemical properties such as solubility.

Complete step by step solution:
M Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Metals in combined state, the metals are said to occur in the combined state if they are found in nature in the form of their compounds. Generally, the reactive metals occur in the form of their compounds. In the combined state the metals are found in the crust of the earth as oxides, carbonates, sulphides, silicates, phosphates etc.
Borax mainly helped get rid of stains, mold, and mildew around the house. It can kill insects such as ants. It's used in laundry detergents and household cleaners to help whiten and get rid of dirt. It can neutralize odors and soften hard water.
Borax may be an element compound. Following are a number of the uses of borax:
Mineral is usually utilized in laundry and cleanup products. Once treated with acid it forms element acid. Borax is employed as a precursor in many industrial applications. It’s additionally utilized in the food, chemical, and pharmaceutical industries. The reaction to produces element acid is as shown below,
$N{{a}_{2}}{{B}_{4}}{{O}_{7}}\cdot 1\text{ }0\text{ }{{H}_{2}}O\text{ }+\text{ }2\text{ }HCl\text{ }\to \text{ }4B{{\left( OH \right)}_{3}}\text{ }+\text{ }2NaCl\text{ }+\text{ }5{{H}_{2}}O\text{ }$
Mineral additionally has disinfectant properties. It’s wont to clean and destroy unwanted pests.
Mineral is employed as a married woman material for scientific discipline processes.
Within the biological application of organic chemistry, minerals are employed for the assembly of buffer solutions. Mineral is {employed} because the antifungal is so employed to kill fungi and stop its growth.
Tincal, also called borax is sodium tetraborate deca-hydrate with chemical formula $N{{a}_{2}}{{B}_{4}}{{O}_{7}}.10{{H}_{2}}O$
Therefore, correct answer is option C, i.e. $N{{a}_{2}}{{B}_{4}}{{O}_{7}}.10{{H}_{2}}O$

Note:
Note that the mineral is a naturally occurring substance, representable by a chemical formula, which is usually solid and inorganic, and has a crystal structure. It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition; examples are Dolomite, Bauxite, Magnetite, etc.
