Chemical salts are ionic compounds formed from the combination of a cation with an anion. These compounds have a wide variety of uses in industry, medicine, agriculture and other fields.

Salts are formed through a chemical reaction between an acid and a base. During this reaction, the acid and base ions exchange charges to form a salt. For example, the combination of hydrochloric acid and sodium hydroxide produces sodium chloride (common salt) and water:

HCl + NaOH → NaCl + H2O.

Salts can have different properties, such as melting and boiling point, solubility, density and electrical conductivity. These properties depend on the chemical structure of the salt and the forces that exist between the ions in the crystal lattice.

Salts are used in a wide variety of applications. For example, sodium chloride is used as a seasoning and preservative in the food industry, as a flux in metallurgy and as a raw material in the production of other chemical compounds. Aluminum sulfate is used in water purification as a coagulant and flocculant to remove impurities. Ammonium nitrate is used as a fertilizer in agriculture and as an explosive in mining.

Salts also have applications in medicine. For example, potassium chloride is used to treat hypokalemia (low potassium in the blood) and magnesium sulfate is used as a laxative and in the treatment of eclampsia (complication of pregnancy).

Below are several simulations and other educational resources, which can also serve as very illustrative examples. In addition, a selection of books and courses is included to help you broaden your knowledge of this subject.

Silver arsenate

Silver arsenate is an inorganic compound with the formula Ag3AsO4. It has been used in qualitative analysis to distinguish between phosphate and arsenate solutions.

Mercury(I) Bromide

Mercury(I) bromide is a chemical compound with the chemical formula Hg2Br2. It changes color from white to yellow when heated and fluoresces salmon-colored when exposed to ultraviolet light. It has applications in acoustic-optical devices.

Strontium Phosphate

Strontium phosphate is a chemical compound with formula O8P2Sr3. It is a crystalline substance used in medicine and industry.

Silver Bromide

Silver bromide is a chemical compound, whose formula is AgBr, widely used in the field of photography due to its sensitivity to light.
