Summary: Discover the amazing world of CBSE Class 12 Chemistry Investigatory Projects! Dive into exciting chemical experiments, insightful analysis, and unexpected discoveries. Explore a variety of fascinating topics that ignite your scientific curiosity. 

Chemistry is one of the most fascinating science subjects. Chemistry is engaged in practically every aspect of our daily lives. It's always fascinating to discover how chemical reactions affect our lives. 

A chemical investigational project is a scientific investigation aimed at investigating a specific topic or question. It usually entails performing research in the discipline of chemistry as part of a scientific fair or an individual study. 

Examining the qualities of a novel material, analysing the chemical composition of a specific item, or evaluating the efficiency of a newly established technique for synthesising a chemical molecule are all examples of CBSE class 12 chemistry investigatory projects. 

Designing and executing experiments, systematically analysing the collected results, and finally presenting the findings through a detailed report or a well-structured presentation are all part of the process of completing a CBSE class 12 chemistry investigatory project.  

We give an extensive list of popular CBSE class 12 chemistry investigatory project topics that students might explore in their studies in the sections that follow.

10 Most Popular CBSE Class 12 Chemistry Investigatory Project Topics  

Because you have less time to study for your board examinations, it is best to prepare your chemistry project so that it is easy to explain. The most common chemistry project for class 12 is described here. 

  1. Adsorption  

A process that leads to the transfer of a substance from fluid bulk to a solid surface, because of the forces of chemical bonds is called Adsorption. In this, the gaseous or liquid particles bind to a solid surface called adsorbate and form a molecular or atomic adsorbate film. Adsorption is usually a reversible process and in most cases, it is described at equilibrium which quantifies the amount which is equal to the amount of substance attached to the surface given and the concentration in the fluid. This is a popular concept among students for the chemistry project for class 12. 

  1. Synthesis of Aspirin 

One of the choicest Chemistry projects for class 12 students is the making of Aspirin which is a common name for a compound named acetylsalicylic acid, majorly used as a pain killer in our day-to-day use. It is derived from salicylic acid, which is a natural product originating from the bark extracts of the willow family of plants, and was earlier used as a home remedy for curing headaches and fever. As the salicylic acid is bitter and irritating for the stomach, it is administered in the form of aspirin which proves to be less irritating.

  1. Analysis of Fertilizer 

Aim: The objective of this experiment is to examine the refractive index of water using a travelling microscope. 

Theory: Refraction is a phenomenon when the direction of light changes while traveling from one transparent medium to another. A refractive index is measured by calculating the ratio of the velocity of light from one medium to another.  

Requirements:  A beaker, a paper piece, a coin, and a traveling microscope. 

  1. Effect of Potassium Bisulphate as a Food Preservative 

Aim: The objective of this project is to analyze the effect of Potassium bisulfite as a food preservative under different conditions. 

Theory: Different food materials undergo natural changes due to environmental factors like temperature, time, and enzymes which make them decayed or inconsumable. The use of potassium bisulphite (KHSO3) effectively can preserve the food material by checking its concentration under different conditions. 

Requirements: Beaker, glass bottles, balance, peeler, pestle and mortar, fresh fruits, knife, potassium bisulphite and sugar. 

  1. Sterilization of Water Using Bleaching Powder 

Aim: The following experiment is conducted to determine the quantity of bleaching powder required for the sterilization or purification of different samples of water. 

Theory: Bleaching powder or Calcium hypochlorite [Ca(ClO)] is a very common way to disinfect drinking water with accurate scientific details. By using 5 drops of bleaching power for 2 litres of water, the chemical is set to sit for half an hour which can then make it safe for drinking. Bleaching powder also reacts with decaying levels and has lesser health risks than other chemical compounds like THMs. 

Requirements: 250ml measuring flask, weight box, Burette, titration flask, 100ml graduated cylinder glazed tile, glass wool, bleaching Powder, 10% KI solution, Glass wool, Sodium thiosulfate solution (0.1 N Na2S2O3), different samples of water, starch solution.

  1. Extraction of various essential oils present in Ajwain (Carum), Illaichi (Cardamom), and Saunf (Fennel Seeds) 

Aim: To extract essential oil present in  Ajwain (Carum), Illaichi (Cardamom), and Saunf (Fennel Seeds) 

Theory: Essential oils have pleasant odours and are used are flavouring agents in food. They comprise complex mixtures and are also useful in insecticides and medical purposes. They are mostly concentrated in seeds or flowers but can be extracted from plants by steam distillation which reduces the risk of decomposition of essential oils.  

Requirements: Round bottom flask (500 ml), conical flask, Steam generator (Copper Vessel),  condenser, glass tubes, iron stand, sand bath, separatory funnel, tripod stands, burners, Ajwain(Carum), Petroleum ether(60-80°C), Saunf(Aniseed). 

Presence of Oxalate Ions in Guava Fruit and Different Stages of Ripening 

Aim: To analyze the presence of oxalate ions in guava fruit and different stages of ripening. 

Theory: Carboxylic acids- primarily found in animals and plants- are produced in our body by the conversion of Vitamin C to oxalate. Excessive oxalate in our urine can cause hyperoxaluria (kidney stones). 

Requirements: 100ml. Measuring flask burette, pestle and mortar, beaker, funnel, weighing machine, papers, filter, dilute H2SO4, L (N /10) KMnO4 solution. 

  1. Quantity of Presence of Casein in Different Samples of Milk 

Aim: To analyze the Quantity the presence of casein in different samples of milk. 

Theory: Caseins are proteins found in milk and the most common form is sodium caseinate. When milk is kept out for a long time, the bacteria present convert it into lactic acid, making it sour. The casein of milk starts precipitating in acidic conditions.  

Requirements: Conical flask, Funnel, Beakers, Measuring cylinder(100 mL), Watch glass, Filter paper, 1% acetic acid, Different samples of milk, Glass rod.

  1. Surface Chemistry Colloidal Solutions 

Aim: To study the surface chemistry of colloidal solutions. 

Theory: Colloids are homogenous solutions that contain separate phases. The dispersed phase consists of particles that are evenly distributed in the continuous phase. Some colloids exhibit the phenomenon of the Tyndall effect, which makes them translucent (Scattering of light by colloidal particles.). Gums are secreted by stems of trees and are natural polysaccharides. On heating with water, this soluble substance gets hydrolyzed and yields several monosaccharides which leads to a colloidal solution.  

Requirements: Two beakers (250 ml. and 50 ml.), Funnel,  wire gauze,  glass rod, tripod-stand, burner, filter papers, distilled water (100 ml), Arabic gum 4.5 g 

  1. Paper Chromatography 

Aim: To analyze ink components in black markers/pens using paper chromatography. 

Theory: Chromatography is used to separate the components from complex mixtures. Ink manufacturers mix various colours to make newer ones. Paper chromatography helps separate different ingredients by attracting them to alcohol or water.  

Requirements: 100 mL beaker, 500 mL beaker, 90% isopropyl alcohol, Mini binder clips (2), Wooden splints, Different black pens and markers.
