Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

The molar solubility of silver sulfate in a 0.148 M potassium sulfate solution is M.
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.
