How do you conduct a salt analysis?
Procedure: Take a small amount of salt solution in a test tube and add some drops of sulphuric acid (H2SO4) to it. If you observe no change, then you can carry out preliminary tests for Group 2 anions. An odourless and colourless gas is released. It turns limewater milky.
How can you identify a salt?
There is a certain basic procedure to identify a salt that can be followed.
- Look at the Appearance of the Compound.
- Check the Effect of Heating.
- Conduct a Flame Test.
- Test Its Reaction with Hydrochloric Acid.
- Note Its Solubility in Water.
- Sieve analysis.
- Moisture analysis.

What is semi Micro 11 analysis?
: chemical analysis (as of quantities of the order of centigrams) on a scale intermediate between macroanalysis and microanalysis.
What is dry test and wet test in salt analysis?
Dry and wet test of Cation ⇒ Dry tests are those tests which are performed with the solid salt (or a mixture of salts), while wet tests are those tests which are preformed by dissolving the salt. (or mixture of salts) in water, acid or any other solvent.
How do you remember a salt analysis chart?
After getting a positive preliminary test for an anion, a confirmatory test must be conducted to confirm the presence of that anion in the salt….Preliminary Test for Group 1 Anions.
| Anion | Positive Result |
|---|---|
| Carbonate (CO32-) | Colourless and odourless gas that turns limewater milky |
How do you identify an unknown salt?
Students identify unknown chloride salts by (1) using a precipitation reaction to determine if the cation is a group 1 or group 2 metal, (2) performing a titration with silver nitrate to determine the formula mass of the salt, and (3) confirming the identity of the salt using a flame test.
