How can you identify ions in an unsolved solution?

This is how to test water for ions.

Flame tests for ions Testing These include potassium, sodium, and lithium which all react strongly with water and air. To detect the presence an alkali metallic ion, it is possible to use a flame testing. The compound is tested by dipping a clean, moistened flame testwire into a solid sample.

You may also wonder, "What are other methods for anion analysis?" There are two types IC columns that can be used for anion analysis. They are hydroxide selective and carbonate optimized. Carbonate optimized columns are suited for isocratic separation of anions in simple matrices using carbonate or carbonate/bicarbonate eluents.

How do you solve an anion problem?

Anion Testing and Observations First, dilute nitric to get rid of any interfering ions. Next, add an aqueous solution to the test sample. Select an aqueous solution which will precipitate the anion from the test sample. We can confirm the identity of the anion if precipitate is formed.

Why is OH ions used for cation identification?

A ligand exchange reaction is required for transition metals to correctly test and identify cations . To test cations , sodium hydroxide engages and reacts to the metal aquo complex.
