Precautions for salt analysis
WebThe various salts of the cations that you will be studying have varying solubilities in water. The differences in solubilities of these salts can be exploited in such a way as to allow for separation of the cations. As an example, let’s examine the cations calcium, Ca2+, and sodium, Na+. Calcium chloride is readily soluble in water, while calcium WebSalt C is ammonium carbonate, (NH 4) 2 CO 3. The bubbling and limewater test shows that CO 3 2- ions are present. The test with sodium hydroxide solution and litmus paper shows …
