Popular Chemistry Project for Class 12
Since you have got comparatively lesser time to study for your board exams, it is advisable to prepare your chemistry project easy and simple to explain. Given below are the details about the most popular chemistry project for class 12.
A process that leads to the transfer of a substance from fluid bulk to a solid surface, because of the forces by 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 on the surface given and the concentration in the fluid. This is a popular concept among students for the chemistry project for class 12.
Synthesis of Aspirin
One of the choicest Chemistry projects for class 12 studnets is the making of Aspirin which 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 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.

Here are some of the chemistry projects for class 12th explained briefly:
Sterilization of Water Using Bleaching Powder
Aim: The following experiment is conducted to determine the quantity of bleaching powder required for 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.
Analysis of Fertilizer
Aim: The objective of this experiment is to examine the refractive index of water using a traveling microscope.
Theory: Refraction is a phenomenon when the direction of light changed while traveling from one transparent medium to another. A refractive index is measured by calculating the ratio of the velocity of light of one medium to another.
Requirements: A beaker, a paper piece, a coin, a traveling microscope.
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 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.
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 makes 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.
Quantity of Presence of Casein in Different Samples of Milk
Aim: To analyze the Quantity of 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 out 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.
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: The essential oils have pleasant odors and are used are flavoring 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 if 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).
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 a number of 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
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 colors 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.
Nano-gold for Cancer Therapy
Aim: To study the potential application of nano-gold for cancer therapy.
Theory: The latest method of cancer treatment includes using particles of nano-gold to absorb light from infrared lasers and destroy a tumour. It is slightly challenging because the light must not harm the healthy tissues.
Requirements: Vial of nano-gold (red, pink, blue) suspensions, Vial of water with yellow food colouring, Flask of coloured water (red, pink, blue), LED flashlights, Magnet board (from Seeing Scale), Red theatrical gel.
Electrolyte Turns on the Solar Cell
Aim: To study how electrolytes and different objects influence the solar cell’s output energy.
Theory: The solar cells have more energy output when the material is blended well. Through this experiment, various objects and substances with different measures are used to impact the output energy of a solar cell.
Requirements: 10 ml vinegar, 6g Titanium Dioxide, dishwashing detergent, TiO2 solution, berries, water, glass slides, multimeter.
