Chemistry Investigatory Projects for Class 12: An investigatory project in chemistry is a scientific study that aims to investigate a particular problem or question.
It is a type of research project that is typically completed as part of a science fair or as an independent study.
Some examples of chemistry investigatory projects might include studying the properties of a new material, analyzing the chemical composition of a particular substance, or exploring the effectiveness of a new method for synthesizing a chemical compound.
To complete a chemistry investigatory project, you will need to design and conduct experiments, analyze the results of your experiments, and present your findings in a report or presentation. Here we have provided information about different chemistry investigatory projects that students can choose for themselves.

It was earlier employed as a home remedy for curing fever and headaches. Salicylic acid can irritate your stomach and is bitter in taste.
In this process, gaseous or liquid particles attach to a solid surface called adsorbate and create a molecular or atomic adsorbate film.
Adsorption is generally a reversible process. In most cases, it is explained at equilibrium, which measures the amount equal to the amount of substance joined on the given surface and application in the fluid. It is a famous concept among students for Chemistry Investigatory Projects for Class 12.

Below are some of the Chemistry Investigatory Projects for Class 12-
Theory: Calcium hypochlorite [Ca(ClO)] or bleaching powder is a very frequent way to sterilize drinking water with exact scientific details. By adding five drops of bleaching powder to two liters of water, the chemical sets for 30 minutes which can then make it drinkable.
Bleaching powder also reacts with decaying levels and has fewer health threats than other chemical compound solutions such as THMs.
Requirements: 10% KI solution, 250ml measuring flask, glass wool, weight box, different samples of water, Burette, titration flask, Sodium thiosulfate solution (0.1 N Na2S2O3), 100ml graduated cylinder glazed tile, bleaching Powder, starch solution.

Theory: Caseins are proteins present in milk. It is the most common form is Sodium caseinate.
When we keep milk outside for a long period, the bacteria found in it transform it into lactic acid, making it sour in taste. The Casein of milk begins precipitating in acidic circumstances.
Requirements: Filter paper, Conical flask, different samples of milk, funnel, Watch glass, Glass rod, Measuring cylinder (100mL), 1% acetic acid.
Theory: Chromatology is employed to divide the components of complex combinations. Ink manufacturers blend different colors to make new ones. Paper chromatology assists in separating different components by attracting them to water or alcohol.
Requirements: 90% isopropyl alcohol, 100 mL beaker, 500 mL beaker, Different black pens, and markers, Mini binder clips (2), Wooden splints.
Theory: Different food materials go through normal changes because of environmental factors, such as time, temperature, and enzymes, which made them inconsumable or perished. The use of potassium bisulphite (KHSO3) can conserve food materials by examining its concentration under different conditions.
Requirements: Beaker, pestle and mortar, glass bottles, peeler, fresh fruits, knife, balance, potassium bisulphite, and sugar.
Theory: Collides are homogeneous solutions comprising separate phrases. The separated fees comprise particles that are equally distributed in the constant phase. Some colloids display phenomenon of the Tyndall effect, making them transparent. It means the scattering of light by colloidal particles. Gums are released by stems of trees and are natural polysaccharides. On heating with water, this soluble substance gets hydrolyzed and defers various monosaccharides, leading to a colloidal solution.
Requirements: 100 mL beaker, 90% isopropyl alcohol, 500 mL beaker, Different black pens, and markers, Mini binder clips (2), Wooden splints.

These help you test your own yourself and help you prepare for your exams in a better way.Popular Chemistry Investigatory Projects for Class 12
We suggest preparing your Chemistry Investigatory project simple and easy to understand because you have comparatively less time to study for your board exams as they are on your head.Following are the details about the most popular Chemistry Investigatory Projects for Class 12-
Synthesis of Aspirin
One of the most popular Chemistry Investigatory Projects for Class 12 students is the making of aspirin, a common name for a compound, named acetylsalicylic acid. It is mainly used as a painkiller in our daily lives. Aspirin is derived from Salicyclic acid, a natural product, having its roots from the bark extracts of the Willow family of plants.It was earlier employed as a home remedy for curing fever and headaches. Salicylic acid can irritate your stomach and is bitter in taste.
Adsorption
Adsorption is a process of transferring a substance from fluid bulk to a solid surface due to the forces of chemical bonds.In this process, gaseous or liquid particles attach to a solid surface called adsorbate and create a molecular or atomic adsorbate film.
Adsorption is generally a reversible process. In most cases, it is explained at equilibrium, which measures the amount equal to the amount of substance joined on the given surface and application in the fluid. It is a famous concept among students for Chemistry Investigatory Projects for Class 12.

Sterilization of water using bleaching powder
Objective: This experiment helps examine the quantity of bleaching powder needed for the sterilization or purification of various samples of water.Theory: Calcium hypochlorite [Ca(ClO)] or bleaching powder is a very frequent way to sterilize drinking water with exact scientific details. By adding five drops of bleaching powder to two liters of water, the chemical sets for 30 minutes which can then make it drinkable.
Bleaching powder also reacts with decaying levels and has fewer health threats than other chemical compound solutions such as THMs.
