Acid is a complex substance containing one or more hydrogen atoms and an acidic residue.
The presence of hydrogen atoms in acid molecules is common to all acids. It is the hydrogen atoms that determine the properties of acids. The H number is the acid basicity.
Acids differ in the composition of the acid residue:
A) oxygen-containing ones have oxygen atoms in the acid residue: HNO3, H2SO4, H3PO4, H2CO3, H2SiO3.
B) oxygen-free ones do not have it in their composition: HCl, H2S, HJ, HBr, HF.
