Top 8 CBSE Class 12 Chemistry Investigatory Project Topics 2024
The most popular CBSE class 12 chemistry investigatory project topics have been shared below:
1. Sterilising water with the use of bleaching powder
Objective: The experiment aims to determine the amount of bleaching powder needed for purifying or sterilising various samples of water.
Requirements: Burette, weight box, titration flask, measuring flask (250 ml), graduated cylinder (100 ml), glazed tile, bleaching Powder, glass wool, 10% KI solution, Sodium thiosulfate solution (0.1 N Na2S2O3), starch solution, Glass wool, different water samples
Theory: Drinking water is most commonly purified using bleaching powder or sodium hypochlorite. 5 drops of bleaching powder is added to 2 litres of water. The water is kept for 30 minutes to allow the chemical to disinfect the water, thereby making it fit to drink. Bleaching powder has fewer health risks as compared to other chemicals.
2. Surface chemistry of colloidal solutions
Objective: The experiment aims to understand the surface chemistry of colloidal solutions.
Requirements: Beaker 1 (250 ml), Beaker 2 (50 ml), distilled water (100 ml), wire gauze, funnel, glass rod, burner, tripod-stand, filter papers, Arabic gum (4.5 g)
Theory: Colloids are said to be homogenous solutions containing different phases. The dispersed phase contains particles which are distributed evenly in the continuous phase. Some colloids also exhibit the Tyndall effect which is the phenomenon of light being scattered by colloidal particles, making them translucent. Gums are secreted by the stems of trees. These gums are natural polysaccharides. When heated with water, this soluble substance becomes hydrolyzed, therefore producing numerous monosaccharides. This results in a colloidal solution.
3. Extraction of the essential oils from fennel seeds, cardamom, and carum
Objective: The experiment aims to extract the essential oils in fennel seeds, cardamom, and carum
Requirements: Conical flask, round bottomed flask (500 ml), condenser, steam generator (copper vessel), iron stand, glass tubes, separatory funnel, sand bath, burners, tripod stands, carum, cardamom, aniseed, petroleum ether (60-80°C)
Theory: Essential oils are used in foods as flavouring foods because of their pleasant smells. They consist of complex mixtures. These essential oils are extracted from the seeds and flowers by the method of steam distillation. This method of extraction prevents the essential oils from decomposing.

4. Paper chromatography
Objective: The experiment aims to understand the components of ink in the pens and markers through the method of paper chromatography
Requirements: Beaker 1 (500 ml), Beaker 2 (100 ml), Wooden splints, 90% Isopropyl alcohol, Mini binder clips (2), markers , black pens
Theory: Chromatography is the method of separating the component from the complex mixtures. Several different colours are mixed to form new colours by the ink manufacturers. Various components present in the ink are separated through chromatography, which involves attracting the components to water or alcohol.
5. Amount of casein in different milk samples
Objective: The experiment aims to measure the quantity of casein present in different samples of milk
Requirements: Funnel, conical flask, beakers, watch glass, measuring cylinder (100 ml), filter paper, different samples of milk, 1% acetic acid, glass rod
Theory: Caseins are a form of protein. These are present in milk in very high quantities. The most common type of casein that is found in milk is sodium caseinate. When the milk is unrefrigerated for a very long time, it curdles because bacteria turns it into lactic acid. When exposed to acidic conditions, the casein of milk precipitates.
6. Presence of oxalate in guava
Objective: The experiment aims to analyse the presence of the oxalate ions in guava together with the different ripening stages
Requirements: Measuring flask (100 ml), burette, beaker, pestle and mortar, funnel, weighing machine, filter, papers, (n/10) KMnO4 solution, dilute H2SO4
Theory: Carboxylic acid is a form of acid which is mostly present in animals and plants. It is also present in the human body. During the ripening of guava, the oxalate ions present in the fruit increase at a very fast rate. At a stage when the fruit is the ripest, the amount of oxalate ions present in it is maximum.

7. Potassium bisulphite as food preservative
Objective: The experiment aims to analyse the role of potassium bisulphite as a preservative of food under varying conditions
Requirements: Beaker, balance, glass bottles, peeler, fresh fruits, pestle and mortar, knife, sugar, potassium bisulphite
Theory: Different kinds of foods undergo chemical changes under standard conditions of temperature, and pressure, and because of various enzymes present in the natural environment. This renders the food unfit for consumption. Potassium bisulphite is used as a preservative for food, preventing the decomposition of food under standard temperature and pressure.
8. Analysing a fertiliser
Objective: The experiment aims to analyse the amount of fertiliser which should be used to yield maximum produce that is economically viable for the producer.
Requirements: Different fertilisers such as urea, superphosphate of lime, ammonium sulphate, calcium ammonium nitrate, etc.
Theory: A fertiliser can be a nitrate mixture or a manure. Fertilisers are used to yield good produce of crops. These are used in the soil to increase its fertility thereby helping the plants and crops give better yield. Fertilisers are the components which are responsible for increasing the fertility of the soil by adding potassium, phosphorus, nitrogen, etc. to help the plants produce better quality and quantity of crops.
