Learn how to make different concentrations of molar and normal sodium chloride solutions, which are needed for many applications such as research, practical, pharmaceutical, chemical laboratory, and industries, etc.
Sodium chloride, also known as salt, is an ionic substance having the chemical formula NaCl with a sodium and chloride ions ratio of 1:1. It is a crystalline solid with an fcc structure, and it contains four ions of each Na+ and Cl-.
The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) produces NaCl. In this reaction, both the acid and the base are strong. It can be found in the oceans and seawater, as well as in rock salt.
It is used in medicine (saline solution), fire extinguishers, the textile industry, and the paper industry as well as to produce sodium carbonate, and also used in water softening, etc.
Generally, a solid form of sodium chloride (NaCl) in different-sized packs is supplied in the market by vendors in the form of white/colorless crystalline or cubic crystals that are usually about 98-100% pure.
Requirements of glassware, chemicals, and apparatus:
Digital balance, beaker, pipette, pipette bulb, volumetric flask, measuring cylinder, glass rod, funnel, distilled water, AR/LR grade sodium chloride (NaCl), etc.
Calculation method:
In this case, we must determine the mass of sodium chloride (NaCl) required to make 1 molar solution of NaCl as well as the volume of the solution. We must use the molarity formula, which is,
Molarity= Moles of solute/Volume of solution
Step-by-step complete answer:
We must first determine the moles of NaCl. The solution is 1 L in volume and has a molarity of 1 M.
So, moles of NaCl can be calculated as,
Moles of NaCl=Molarity × Volume of solution= 1L
Moles of NaCl= 1 M ×1L=1 mol
Therefore, the mole of NaCl in the solution is 1 mol.
The mass of NaCl now is calculated using the number of moles of NaCl.
Number of moles= Mass/Molar mass
The mole of NaCl is 1 mol, and its molar mass is 58.44 g/mol.
1=Mass/58.44g/mol
Mass of NaCl=58.44 g
Therefore, to make a 1 M solution of NaCl, we need to dissolve 58.44 g of sodium chloride in 1 liter of distilled water.
Note:
Because the valency of NaCl is 1, the molarity and normality of the solution are the same.

PRECAUTIONS:
- When working with chemicals, avoid contact with skin, eyes, clothing, ingestion, and inhalation.
- NaCl is hygroscopic in nature it should be stored in a tightly closed container.
- Stir a little amount of sodium chloride into a large volume of water at a time, and then dilute the solution.
- When making sodium chloride solutions, it is recommended that always use distilled water.
- Wear protective gloves, clothing, eye protection, and face protection.
- Wash your hands/skin thoroughly after handling.
- Solutions are highly alkaline and corrosive. Contact can cause serious skin and eye irritation. Therefore should be handled with care, follow laboratory safety measures (SOP/Procedure), and please use extreme caution when preparing the solution concentrations.
