The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Equilibria among double sulfates and aqueous solutions of sulfuric acid of various concentrations. I.》. Authors are Montemartini, C.; Losana, L..The article about the compound:Aluminum(III) sulfate xhydratecas:17927-65-0,SMILESS:O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al]).COA of Formula: Al2H8O13S3. Through the article, more information about this compound (cas:17927-65-0) is conveyed.
Because of the lack of systematic data in the literature on the solubility of sulfates in aqueous H2SO4, a study of double sulfate-H2SO4-water systems was begun with a study of the simple systems containing only a single sulfate. The exptl. data include the dilation of Al2(SO4)3.18H2O, Al2(SO4)3.Na2SO4.24H2O, Cr2(SO4)3.K2SO4.24H2O, AlCl3.6H2O, Al(NO3)3.18H2O, Cr(NO3)3.9H2O, Fe2(SO4)3 and Fe2(SO4)3.K2SO4.24H2O solutions as a function of temperature, the time required for such solutions after being heated to return to their original state, as judged by e. m. f. and internal friction determinations, and the solubility of Al2(SO4)3.18H2O, of Al2(SO4)3.Na2SO4.24H2O and of Cr2(SO4)3.K2SO4.24H2O in aqueous H2SO4 of various concentrations Data for all these determinations are given in graphical form.
