Relative Molecular Mass of Potassium Chloride

The relative molecular mass of potassium chloride is: 74.5.

Relative atomic mass refers to the ratio of the true mass of any atom to 1/12 of the mass of a carbon-12 atom as a standard, which is called the relative atomic mass of that atom. Molecules are made up of atoms, so the relative molecular mass is equal to the sum of all the atomic masses. The chemical formula of potassium chloride is KCl.

So its relative molecular mass is: 39.1+35.45=74.55.

Physical and Chemical Properties of Potassium Chloride:

1, Physical Properties: white crystal, very salty taste, odorless and non-toxic. Easily soluble in water, ether, glycerol and alkali, slightly soluble in ethanol, but insoluble in anhydrous ethanol, hygroscopic, easy to agglomerate; solubility in water increases rapidly with the rise in temperature, and sodium salts are often complex decomposition and the generation of new potassium salts.

2, chemical properties: the chemical properties of potassium chloride is basically the same as sodium chloride, can be decomposed at high temperature, can react with concentrated sulfuric acid to generate potassium bisulfate and hydrogen chloride.

Main uses of potassium chloride:

1, mainly used in inorganic industry, is the basic raw material for the manufacture of various potassium salts.

2. It is used in pharmaceutical industry as diuretics and drugs to prevent and control potassium deficiency.

3. In agriculture, it is a kind of potash fertilizer, which is directly applied to farmland and can make the water in the lower layer of the soil rise, and has the effect of anti-drought.

4. Potassium chloride is similar in taste to sodium chloride (bitter), and is also used as an additive to low-sodium salts or mineral water to reduce the possibility of high blood pressure. In addition, it is also used in medicine, scientific applications, and food processing.
