Abstract
1. A study was made of the reaction with solutions of hydrochloric, nitric and sulfuric acids of vitreous sodium aluminosilicates composed of disilicate with additions of 0.15 to 1 mole Al2O3. 2. Increasing hydrogen ion concentration when using one and the same acid is accompanied by increasing decomposability of those aluminosilicate glasses whose skeleton, due to depolymerization of their silica content, is unstable toward solutions of acids. 3. Vitreous sodium aluminosilicates are decomposed in 0.1 N sulfuric acid solution more rapidly than in hydrochloric and nitric acids of the same concentration. This phenomenon can be explained by the lower degree of electrolytic dissociation in comparison with the corresponding chlorides and nitrates formed in a solution of sodium and aluminum sulfates.
