What are the inorganic compounds?

Inorganic chemical compounds are those that contain a structure different from the mnemonic acronym: “CHONX” (Carbon, hydrogen, oxygen, nitrogen, halogen). Although there are inorganic compounds formed by one or more of the elements mentioned above. As it can be the Carbon (carbon chains), the NH₃, Hypochlorite. We can establish that if the central structure does not contain “CH” it is an inorganic compound with the exception of H₂CO₃.

Inorganic chemicals that may enter the water supply from natural causes or contamination must be evaluated to determine, understand, and apply the standards set by the Health Authority.

Each inorganic compound that dissolves in water is characterized by the health authorities under the following points.

Chemistry
Exposure to the environment
Health effects

The inorganic compounds that can be dissolved in water are classified into four groups, type A, B, C and D.

Type A	Type B	Type C	Type D
Arsenic	Aluminium	Calcium	Antimony
Asbestos	Cyanide	Carbon Dioxide	Beryllium
Barium	Molybdenum	Chlorides	Cobalt
Cadmium	Nickel	Iron	Tantalum
Chrome	Silver	Lithium	Tin
Copper	Sulfate	Magnesium	Thorium
Fluoride	Sodium	Manganese	Vanadium
Lead	Zinc	OD, BOD, COD
Mercury		Phosphates
Nitrate – Nitrite		Potassium
Ammoniacal Nitrogen		Silica
Selenium		Bromine
		Iodine
		Ozone

Type A.

Inorganic chemicals that are classified as type A are those that have a high potential for toxicity and are therefore not expected to be present in drinking water.

Type B.

Inorganic chemicals that fall into this category are those with high toxicity, but which are rare in drinking water and when they do appear they do so in very small concentrations.

Type C.

Inorganic type C chemicals are those that occur frequently in drinking water, and do so in concentrations that are safe for humans. It is rare when they appear above the toxicity limit, but when they do, caution should be exercised.

Type D.

Inorganic chemicals of type D are those that are found in very low concentrations in well water and drinking water, apart from being non-toxic in low concentrations.
