If desired, the mixture was heated gently to increase rate of reaction. The reagents includes the following compounds all having different anions (-ve). To this, 1 drop of the reagent was initially added, followed by the further addition of about 2mls solution, and finally in xs. In 10ml testtubes, 4mls of this clear Strontium solution was placed. Filtering this Strontium solution would prepare a clear solution. When some Strontium Nitrate was dissolved in water, a slight white precipitate was resulted perhaps due a slight contamination. However the verification of 4 or 5 such tests will be enough to confirm Strontium in an unknown sample. For Example with NaOH, many metals give a white ppt., and hence one can't say that the formation of a white ppt of an unknown sample with NaOH is 100% due to Strontium cations. One type of reaction is not enough, to confirm the presence of Strontium, since other metal salts may give the same results. (s) Solid precipitate forming a colour change in soultion A solution of a Strontium salt (Strontium Nitrate) was mixed with an equal ammount of another solution, which give a physical change, usually a colour change due to a precipitation of the Strontium insoluble compound.

PRINCIPLEĪs mentioned, the tests are simple precipitation reactions. With the following set of tests it will be a guide to confirm Strontium without requiring complex procedures or sophisticated equipment. Strontium is difficult to distinguish since it forms quite few insoluble and common precipitates.
