On dissolution of salts in water and aqueous solutions

New concepts of the mechanism of chemical interactions between salts and water (water solutions) are put forward. It is shown experimentally, using tungstates by way of example, that in the most cases heterogeneous reactions in the systems above involve a stage, in which radical particles formed as a result of phase contact take part. The reactions mentioned, exchange reactions between tungstates, of bivalent metals and solutions of sodium carbonate, alkali (or inorganic acid) in particular, occur in the layer of liquid adjacent to the solid phase surface
