Identify 2 Acidic And 2 Basic Radical From The Given Inorganic Mixture.
Identify 2 Acidic And 2 Basic Radical From The Given Inorganic Mixture. This blog is related to the chemistry practical of B.Sc first-year major subject. Acidic radicals are those which have negative charges like CO3–(carbonate), SO4–(sulfate), NO3-(nitrate), etc.,
and alkaline radicals There are those on which there is a positive charge such as NH4+(ammonium ion), Pb2+(lead ion), Fe3+(iron), Cr3+(chromium ion), etc. The basic radicals live in different groups and by a special type of group, reagents are precipitated. From this blog, you will get to know how the practical is written in the file.

Identify 2 Acidic And 2 Basic Radical From The Given Inorganic Mixture.
(Acidic Radical Test)
(Observation Table)
| Serial No. | Experiment | Observation | Result |
| 1. | The solution is acidified by taking a little mixture in a test tube, using a few drops of dilute hydrochloric acid, then adding a few drops of barium chloride to it. | A white precipitate of barium sulfate is formed. | Sulfate ions (SO2−4) are present |
| 2. | Taking a little mixture in a test tube, a few drops of silver nitrate are added to a slightly acidic aqueous solution, then | A white precipitate of silver chloride will form | Chloride ions(Cl−) are present |
(Basic Radical Test)
(Observation Table)
| Serial No. | (experiment) | Observation | Result |
| 1. | It can be detected in the solution by taking a small amount of mixture in a test tube, adding dilute sodium hydroxide solution to it, and heating it slowly. If ammonium ions are present, then | They will be converted into ammonia gas. Ammonia has a characteristic suffocating odor. It also turns moist red litmus paper or damp Universal Indicator paper blue. | Ammonium (NH₄⁺) ions are present |
| 2. | Make a basic solution of the mixture and add the first group of reagents to dilute hydrochloric acid to it. | no precipitate | first group absent |
| 3. | After adding a little dilute HCl to the filtrate of the first group, H2S gas is passed through it. | no precipitate | The Second Group is absent |
| 4. | After removing H2S gas from the second group filtrate, adding a little dilute HCl to it and adding more amount of NH4 Cl and NH4 OH | Brown color precipitate comes | the third group is present |
| 5. | After filtering the precipitate with the help of filter paper, Fe3+, Al3+, and Cr3+ were tested. | ||
| One part is dissolved by adding dilute HCl. Then on adding one drop of potassium hexacyanoferrate K4[Fe(CN)6] solution to it | A dark blue precipitate or solution is obtained. | (Fe3+) iron is present. |
Result:- In the given inorganic mixture, two acidic radicals sulfate (SO₄²-) and chloride (Cl-) are present. And two basic radicals, zero group ammonium ion (NH₄⁺) and third group iron (Fe3+) are present.
