Not illustrated. 1852 Excerpt: ...constituent is present; the solution containing it is mixed with excess of sulphuric acid, evaporated to dryness, and ignited in a platinum crucible; the residue is again treated with dilute sulphuric acid, evaporated to dryness, and again gently ignited; the residue is pure anhydrous sulphate of magnesia, the composition of which is One equivalent of MgO...20.67... 34.07 One ditto 8 03...40.00... 65.93 One do. MgOSo3... 60.67 100 Quantitative estimation as Pyrophosphate.--Muriate of ammonia is added to the solution, then ammonia in excess; should a precipitate hereupon occur, a fresh quantity of muriate of ammonia is added, by which the precipitate is redissolved; solution of phosphate of soda is then dropped into the mixture as long as precipitation takes place. The whole is well agitated, and allowed to repose for several hours: the precipitate is collected on a filter, the amount of ash furnished by which is known, and washed with water containing about one-eighth of ammonia, in which thebasic phosphate of magnesia and ammonia (P05 2MgO, NH 0 + 24 aq.) is scarcely sensibly soluble; the washed salt is dried and carefully ignited, together with the filter; the latter requires considerable time for incineration, which is best effected by cutting in strips and burning it on the lid of the crucible. The composition of the ignited salt is Two equivalents of MgO...41.34...36.46 One ditto of PO, ...72.02...63.54 One do. of 2 MgO, P05... 113.36 100 Separation of Magnesia from Baryta find Strontia.--The two latter earths are precipitated by carbonate of ammonia, a sufficient quantity of sal ammoniac having previously been added to the solution to prevent the precipitation of the magnesia: the precipitated carbonates of baryta and strontia are dissolved in hyd.
