Solution is a homogeneous mixture of a liquid (the solvent) with a gas or solid (the solute). In a solution, the molecules of the solute are discrete and mixed with the molecules of solvent. There is usually some interaction between the solvent and solute molecules. Two liquids that canmix on the molecular level are said to be miscible. In this case, the solvent is the major component and the solute the minor component.
Hydrolysisisa chemical reaction of a compound with water. For instance, salts of weak acids or bases hydrolyse in aqueous solution, as in
NaCH3COO + H2O = Na+ + OH- + CH3COOH
The reverse reaction of esterification is another example.
The sodium hydrogencarbonate is heated to give sodium carbonate and carbon dioxide. The ammonium chloride is heated with calcium oxide (from the first stage) to regenerate the ammonia. The process was patented in 1861 by the Belgian chemist Ernest Solvay (1838-1922).
