Magnesium oxide properties Dissolution

Magnesium Oxide In some cases, metal oxides are converted to a more soluble chemical and dissolve more rapidly. For example, magnesium oxide is relatively insoluble in water, but is converted to a more soluble carbonate form by exposure to body fluids whose buffer is bicarbonate (25). This would be expected to enhance the dissolution of magnesium oxide nanoparticles (25). However, titanium dioxide s most soluble form is the acid chloride. If the particles were porous, the porosity (access to the internal surface area) could enhance solubility stiU further for MgO. Empirical evidence suggests that the aggregated-agglomerated metal oxide nanoparticles have minimal reduction of measured surface area, or solubUity properties that parallel such surface areas.
