This is a list of some qualitative laboratory tests that can be used to identify unknowns in lab. ... Anion - An ion with a negative charge, formed when an atom gains electrons in a reaction (it now has more electrons than protons). Non-metals tend to form anions. ... Cation - An ion with a positive charge, formed when an...

For example, if you found that in the cation tests you got the same test result as for Ca2+ and in the anion tests you got the same result as for Cl-, then the ions in your unknown salt would be Ca2+ and Cl-. The formula CaCl2 is written using charge balance.

There is a variety of simple chemical tests we can use to find out what ions are present in a solution. We can test for common anions (negative ions) as shown in the table below.

Cation Anion Tests. Notes Chemistry study guides ... Tests for Anions ... Tests for chloride | ClAdd silver ions and you get a white ppt. of silver chloride. When you add dilute nitric acid or barium nitrate there is no reaction. Tests for carbonate | CO3 2Add dilute nitric acid and bubbles of carbon dioxide gas evolve.

(1992a, 1992b) compared the mixed cation-anion resin method with seven other soil tests and found the mixed method was best for assessing the available P status of soils treated with two PRs varying in reactivity.
