Glacial acetic acid is pure acetic acid, not mixed with water. The smell of glacial acetic acid is much stronger than that of dilute acetic acid. Other than the greater intensity, the smell is exactly the same.
Some say that pH stands for the "power of hydronium," (or hydrogen) but this is disputed. Other interpretations include "percentage of hydronium" or "potential of hydronium," with hydronium interchangable with "hydrogen." The "p" could also be a constant that means "the negative log of" as in pKa.
All acids are divided into two groups. Organic acids and mineral acids. Organic acids are from nature (plants and animals) and mineral acids are made from chemists and scientists.
Both Hydrochloric Acid and Sulfuric Acid will corrode steel. HCl is used as a "pickling agent" for steel by converting rust (Iron Oxide) to Ferrous Chloride. H2SO4 is also capable of attacking Iron and Magnesium to form Metal-Sulfate mineral complexes.
The corrosion rate of steel in sulfuric acid depends on temperature and concentration. In storage tanks and pipes the corrosion rate is also a function of flow velocity.
but if you try flourosulphuric acid then it will literally make the steel disappear....
and acids like carborane and magic acid these are strongest acids
