    Dissociation of acids

    As we remember from chemistry course grade 7 (and someone probably read about it for the first time), the acid is a complex substance containing a hydrogen atom capable of substitution on the metal atom and the acid residue. It turns out that the ability to replace the hydrogen atom to the metal atom is linked to the process of dissociation. If we imagine that the acid is composed of n atoms of hydrogen and acid residue A, it turns out that these n hydrogen atoms by dissolving the acid in water, one detached from the acid residue A in the form of positively charged hydrogen ions (H +). Depending on the nature of the acid residue, the process may proceed to 100%, i.e. completely irreversible (and we are talking about strong acids), and it happens that it takes place completely. Then we are talking about weak acids
