Salt Analysis Class 12 Practical PDF Summary
Dear readers, here we are offering Salt Analysis Class 12 Practical PDF to all of you. Salt analysis (Acidic and Basic radical test) is done to find out the acidic and basic radicals present in it. The salt analysis is a qualitative analysis. By salt analysis, it is determined which cation and anion are present in a given salt sample.
A small quantity of salt is tested by mixing various reagents in a test tube, then the color of the gas produced in it, odor, pungency or color of the solution, precipitate, solubility of the precipitate, etc. from the observations, some conclusions are drawn from which the salt present in the salt. The acidic radical (Anion) or the basic radical (Cation) can be detected. The salt analysis is also called qualitative analysis.

- Tricks and Shortcuts for Salt Analysis
Always check the colour of the salt first. Certain cations have colored salts. If the salt is coloured, you can directly conduct a preliminary test for the cation that forms salts of that colour. The cations that form coloured salts are tabulated below:
|Color of the Inorganic Salt||Cation|
|Deep blue||Co2+ (anhydrous salt)|
|Greenish-blue||Cu2+ (hydrated salt)|
|Green||Ni2+ (hydrated salt)|
|Yellow, brown, or yellowish-brown||Fe3+|
|Rose-red||Co2+ or mercuric iodide (HgI2)|
|Purple or dark green||Cr3+|
