Mineral Acid List and Definition   Recently updated !

Mineral acids tend to be colorless in pure form, although there are exceptions.

A mineral acid is an inorganic acid from a mineral or other inorganic source that dissociates in water to yield a hydrogen ion (H+ or proton) and conjugate base. Mineral acids are important in chemistry and industry because the group includes many useful bench acids. Also, many of these acids serve as feedstock for making both organic and inorganic chemicals.

Mineral Acids List

Mineral acids range from very weak acids (boric acid) to superacids (perchloric acid). Some acids are monoprotic (hydrochloric acid), while others are diprotic (sulfuric acid) or even triprotic (boric acid). Here is a list of mineral acids:

  • Aqua regia (mix of hydrochloric and nitric acid)
  • Boric acid (H3BO3)
  • Hydrobromic acid (HBr)
  • Hydrochloric acid (HCl)
  • Hydrfluoric acid (HF)
  • Hydroiodic acid (HI)
  • Nitric acid (HNO3)
  • Perchloric acid (HClO4)
  • Phosphoric acid (H3PO4)
  • Sulfuric acid (H2SO4)
  • Xenic acid (H2XeO4)

Mineral Acid Properties

In contrast to mineral acids, there are other acids that are either organic or else don’t yield hydrogen. For the most part, you can identify mineral acids by having hydrogen in their formula, but lacking carbon. For example, fulvic acid (C135H182O95N5S2) is an organic acid rather than mineral acid, even though it is derived from soil. This is because fulvic acid comes from the organic portion of soil (humus), contains carbon, and dissociates to yield hydrogen cations.

Two noteworthy properties of mineral acids are solubility and corrosivity. Mineral acids tend to be soluble in water, but not soluble in organic solvents. They are highly corrosive.
