HYDROLYSIS OF SALTS OF DISTINCT NATURE
FSBEI HE USPTU, Ufa, the Russian Federation
The ionization theory attributes this phenomena to the interaction of water ions with the ions of dissolved salts, resulting the formation of an excess of hydrogen or hydroxyl ions. The concentration of hydrogen or hydroxyl ions in water is very low, they are in equilibrium with an immense number of unionized water molecules. When one of them is bound by the ions of the salt, the equilibrium is disturbed, causing new water molecules to ionize, which leads to accumulation an excess of quantities of the other ion, making the solution react acid or alkaline.
Any salt can be obtained by neutralization of acids by bases. It is natural to assume, therefore, that solutions, at least those witch are products of complete displacement of hydrogen in acids by metals, must react neutral. However, this assumption holds only for salts of strong acids and strong bases. Salts of weak acids and strong bases, or vice versa, of strong acids and weak bases, do not react neutral when dissolved in water.
The methods handbook covers the basic material on the subject ”Hydrolysis of salts of distinct nature” that may reasonably be required from Ordinary Level university standard for the trade 18.03.01 “Engineering chemistry”, in particular, when making a study in Ufa State Petroleum Technological University.
