(0.7] General solubility rule for lonic compounds in water tells us that potassium sulfate is soluble inwater while strontium sulfate is insoluble. Describe further what actually happens whenpotassium sulfate is mixed with water and becomes completely dissolved to make the aqueoussolution while the same does not happen to strontium sultate (nothing dissolved in water).

The solubility is the maximum amount of solute that can dissolve in a known quantity of solvent at a…

Ammonium sulfate is added to an unknown mixture of ions. A precipitate forms. The solution is centrifuged, and the remaining solutions is decanted. Ammonium oxalate is then added to the solution and a precipitate forms. The solution is centrifuged, and the remaining solution is decanted. Sodium monohydrogen phosphate and sodium hydroxide are added to the decanted solution, and a precipitate forms. The precipitate is centrifuged and decanted. The solid is dissolved in acid, magnesium indicator is added, then sodium hydroxide is added until the solution turns cloudy blue, which settles when centrifuged. Sodium hydroxide is added to a fresh sample of the unknown. A damp piece of litmus paper over the opening of the test tube remains red. Select the ions present.
