Oct 12, 2005 · In this article we will discuss applications utilizing bentonite’s unique properties in construction. Physical Properties of Bentonite: Two basic bentonite properties – thixotropy and extremely high capabilities for water-absorption are a large part of the basis for successful bentonite application in construction. Many of the characteristics of seawater correspond to those of water in general, because of their common chemical and physical properties. For example, the molecular structure of seawater, like that of fresh water, favours the formation of bonds among molecules. Some of the distinctive qualities of seawater are attributable to its salt content.
Chemical properties of water. The chemical formula of a molecule of water is H2O: two atoms hydrogen (H2) linked to one atom oxygen (O). The atom electrons (particles with a negative charge) establish links between themselves. Oxygen is more able to keep them close to it than hydrogen.Effect of salt content on chemical and physical properties and implications for organoleptic properties.
