Difference Between Ammonium Chloride and Sodium Chloride

Thekey difference在氯化铵和氯化钠之间是在高温下加热氯化铵后，它会产生白色致密烟雾，而加热时氯化钠则不会产生任何白色烟雾.

氯化铵和氯化钠是高度的白色晶体吸湿性. In other words, these are white crystals that look similar and can absorb water upon exposure to moisture in the air.

什么是氯化铵？

Ammonium chloride is an inorganic compound having the chemical formula NH4Cl. It appears as a white crystalline solid compound that is highly soluble in water. Therefore, we can observe that ammonium chloride is a highly hygroscopic material. Due to the ability of the NH4+ cation to remove ahydrogen ionin aqueous solution, the aqueous solutions of ammonium chloride are mildly acidic.

When considering the production of ammonium chloride, the most common route is theSolvay过程wheresodium carbonate通过在水存在下，通过二氧化碳，氨气和氯化钠之间的反应产生氯化铵和氯化铵。但是，在商业上，我们可以通过将氨与HCl气或HCl水溶液结合起来产生这种化合物。

Applications of ammonium chloride include using it as a nitrogen source in fertilizers such as chloroammonium phosphate. Moreover, ammonium chloride is useful as a flux in the preparation of metals. In medicine, ammonium chloride is useful as an expectorant.

What is Sodium Chloride?

Sodium chloride is NaCl that has a molar mass of 58.44 g/mol. At room temperature and pressure, this compound appears as solid, colourless crystals. It is odourless. In its pure form, this compound cannot absorb water vapour. Hence, it is not hygroscopic.

氯化钠也是一个盐;我们称之为it a salt of sodium. There is one chorine atom per each sodium atoms of the molecule. This salt is responsible for the salinity of seawater. The melting point is 801◦C while the boiling point is 1413◦C. In sodium chloride crystals, each sodium cation is surrounded by six chloride ions and vice versa. Therefore, we call the crystal system a face-centred cubic system.

This compound dissolves in high polar compounds such as water. Here, water molecules surround each cation and anion. Each ion often has six water molecules around them. However, the pH of an aqueous sodium chloride lies around 7 due to the weak basicity of chloride ion. We can say that there is no effect of sodium chloride on the pH of a solution.

What is the Difference Between Ammonium Chloride and Sodium Chloride?

Ammonium chloride and sodium chloride are highly similar in their appearance, but we can easily identify the difference between ammonium chloride and sodium chloride via heating them. The key difference between ammonium chloride and sodium chloride is that upon heating ammonium chloride at high temperatures, it gives white coloured dense fumes, whereas sodium chloride does not give any white coloured fumes upon heating.

The below infographic shows the differences between ammonium chloride and sodium chloride in tabular form.

概括– Ammonium Chloride vs Sodium Chloride

Ammonium chloride is NH4Cl. Sodium chloride is NaCl. The key difference between ammonium chloride and sodium chloride is that upon heating ammonium chloride at high temperatures, it gives white coloured dense fumes, whereas sodium chloride does not give any white coloured fumes upon heating.
