TABLES OF ELECTIVE ATTRACTIONS, BY DR. YOUNG. 1. TABLE of the Sequences of the Bases with the different Acids. In all mixtures of the aqueous solutions of two salts, each acid remains united to the base, which stands nearest to it in this Table. VOL, I. (4.) A by (1.) Ammonia stands above magnesia when cold. (2.) A triple salt is formed. (3.) Perhaps magnesia ought to stand lower. compound salt is formed, and when hot, magnesia stands above ammonia. (5.) Fourcroy says, that sulphate of strontia is decomposed borate of ammonia. (6.) With heat, ammonia stands below lime and magnesia. (7.) A triple salt is formed. (8.) Fourcroy says, that the muriate of zirconia decomposes the phosphates of barita and strontia. (9.) According to Fourcroy's account, the fluate of strontia decomposes the muriates of ammonia, and of all the bases below it; but he says in another part of the same volume, that the fluate of strontia is an unknown salt. (10.) According to Fourcroy's account of these combinations, barita should stand immediately below ammonia in both of these columns. (11.) With heat, the carbonate of lime decomposes the muriate of ammonia. (12.) According to Fourcroy, the phosphate of ammonia decomposes the borate of magnesia. (13.) Fourcroy says, that the carbonate of lime decomposes the phosphates of potash and of soda. (14.) According to Fourcroy, the carbonate of ammonia decomposes the fluates of arita and strontia. (15.) Fourcroy says, that the sulphite of barita decomposes the carbonate of ammonia. III. A Table of the Sequences of the Acids with different Bases, by Dr. YOUNG. The comparative use of this Table may be understood from an example: If we suppose that the nitrate of barita decomposes the borate of ammonia, we must place the boracic acid above the nitric, between barita and ammonia in this Table, and consequently barita below ammonia, between the fluoric and boracic in the former: hence the boracic and fluoric acids must also be transposed between barita and strontia, and between barita and potash; or if we place the fluoric still higher than the boracic in the first instance, we must place barita below ammonia between the nitric and fluoric acids, where indeed it is not impossible that it ought to stand.
