DBT Activity Title: Analyse the given salt for acidic and basic radicals
No. of Beneficiary: 87 B.Sc I students
Date of Activity: 30th July to 7th August 2024
Venue: UG Chemistry laboratories
Introduction
Salt analysis (also known as systematic qualitative analysis or qualitative inorganic analysis) involves the identification of the cation and anion of an inorganic salt. This is done by conducting a series of tests in a systematic manner and using the observations to confirm the absence or presence of specific cations and anions. This is a topic that several students struggle with. Therefore, we at have channeled our efforts into explaining this topic in a manner that is easy to understand and remember. If questions like “How to do salt analysis?” and “How to remember salt analysis procedures easily?” This article also touches on certain tricks and shortcuts that students can employ to quickly analyze their assigned salts of acidic and basic radicals.
Objectives :
1.To identify acidic and basic radicals using chemical tests (litmus, pH indicators).
2. To understand the importance of radical identification in chemistry.
3. To categorize acidic and basic radical from a given salt sample.
4. To develop laboratory skills and observation techniques.
5. To describe the schemes of qualitative analysis of acidic radicals (anions) and basic radicals (cations)
Planning and Preparation
To prepare the different inorganic salt whose cation and anion you must identify and the respective reagents and chemicals in the laboratory
The organizing committee comprised:
Dr. G.V. Korpe - Principal, Shri Shivaji Science College
• Dr. A.S. Burghate - Head, Department of Chemistry
• Dr. D.D. Khedkar - Coordinator, DBT Star Project
• Dr. P.R. Mandlik - PG Coordinator
• Dr. P. R. Padole - Activity In-charge
• Dr. A. M. Mopari - Activity In-charge
This activity is scheduled for 30th July to 7TH August 2024, and targeted 87 B.Sc. I students who were enrolled in chemistry with combinations in microbiology, environmental science, biotechnology, physics, mathematics, botany, and zoology.
Venue Selection: This activity was carried out in UG laboratories with respective faculty members and students
Materials:
1. Test solutions:
- Acidic radicals: HCl (hydrochloric acid), HNO3 (nitric acid), H2SO4 (sulfuric acid),etc.
- Basic radicals: NaOH (sodium hydroxide), KOH (potassium hydroxide), Ca(OH)2 (calcium hydroxide)etc.
2. Distilled water
3. Litmus paper (red and blue)
4. pH indicators:
- Phenolphthalein
- Methyl orange
5. Burette and pipettes etc.
6. Chemicals: Acids and Bases
7. Other reagents
8. Apparatus and glassware
Procedure:
Note: Separate Script provided to students which briefly explain the radical detection
• Step 1: Obtain the inorganic salt whose cation and anion you must identify.
• Step 2: Conduct preliminary tests for the anion group-wise until you obtain a positive result. Anions and cations are classified into groups that share the same group reagent and therefore, have similar preliminary tests.
• Step 3: Once you get a positive result for a preliminary test for an anion, conduct a confirmatory test for that anion. (If you get a positive result, move on to step 4. If you don’t, go back to conducting preliminary tests for anions.)
• Step 4: Conduct preliminary tests for cations group-wise until you obtain a positive result.
• Step 5: Once a positive result is obtained, conduct a confirmatory test for that cation.
• Step 6: Now that the cation and the anion are identified, obtain the chemical formula of the salt by balancing the charges of the cation and anion. For example, if your cation is Na+ and your anion is Cl–, the chemical formula of the salt will be NaCl.

Execution of the Activity
On the day of the Activity faculty members and students gathered at the designated venue in Shivaji Nagar. The event commenced with a brief inaugural ceremony, which included the following components:
1. Introduction to the DBT activity: Dr. A.S. Burghate provided an overview of the activity objectives and outlined the day's activities.
2. Explanation of experiments: The type of salt analysis explain to Students participated
3. Engagement Activities: Students engaged in practical to separate different acidic and basic radicals from a given salt enthusiastically with some sort tricks.
4. Results : A sample answer format for salt analysis is provided below.
Aim: To identify the acidic radical and the basic radical of the given inorganic salt.
Apparatus Required: Fill as per requirement.
Procedure:
(i) Preliminary Test for Anion:
Experiment Observation Inference
(ii) Confirmatory Test for Anion:
Experiment Observation Inference
(iii) Preliminary Test for Cation:
Experiment Observation Inference
(iv) Confirmatory Test for Cation:
Experiment Observation Inference
Result: The acidic radical is (anion), and the basic radical is (cation). Therefore, the given salt is identified to be (salt).

Learning Outcomes:
1. Identified acidic and basic radicals using chemical tests.
2. Understood the importance of radical identification in chemistry.
3. Developed laboratory skills and observation techniques.
Assessment:
1. Student participation and engagement (70%).
2. Accuracy of observations and recordings (50%).
3. Understanding of chemical reactions and radical identification (95%).
Safety Precautions:
• Keep work area neat and free of any unnecessary objects.
• Never pour chemical waste into the sink drains or wastebaskets
• Always wear appropriate eye protection (i.e., chemical splash goggles) in the laboratory.
• Wear disposable gloves, as provided in the laboratory, when handling hazardous materials.
• Wear apron. And Wear shoes that adequately cover the whole foot.
• Keep your hands away from your face, eyes, mouth, and body while using chemicals.
• In case of an emergency or accident, follow the established emergency plan as explained by the teacher and evacuate the building via the nearest exit.
• Always use a spatula to remove a solid reagent from a container.
Conclusion:
This activity help student to analyse the acidic and basic radical from a given unknown mixture separately and due to short tricks bring interest among students for experimental analysis. Understand the scientific principles, fundamental theories and concepts, Students were actively participated and enjoyed as a informative activity by gaining knowledge.
