CBSE Class 12 Chemistry Projects

CBSE class 12 Chemistry projects: One of the most important fields of science, chemistry, examines the chemical properties, structure, behaviour, and reactions of substances made up of atoms, ions, and molecules, as well as how to harness these reactions to create new substances. A project can aid a student in quickly grasping the intricate organisation of a subject. CBSE class 12 Chemistry Projects and models that are well-structured provide excellent explanations and make it easy for students to understand the rationale behind laws, derivations, equations, etc.

These projects can help students learn the theory and its applications in an interesting way. Hence, it is imperative that the students do the projects properly. In this article we’ve included some of the important CBSE class 12 Chemistry projects to help the students. 

CBSE Class 12 Chemistry Projects: Overview

Before moving on to the details on CBSE Chemistry projects for class 12, let us have an overview of CBSE class 12 exams. 

Chemistry Practical Project for Class 12

Here are some of the most popular chemistry investigatory project class 12 that the students can try. 

• Sterilisation of Water using Bleaching Powder

Aim: Water Sterilisation Using Bleaching Powder Objective: The purpose of the following experiment is to establish the amount of bleaching powder necessary to sterilise or purify various water samples.

Theorem: According to precise scientific information, bleaching powder or calcium hypochlorite [Ca(ClO)] is a very popular element to purify drinking water. The water can be made safe for drinking by adding 5 drops of bleaching powder to 2 litres of water and letting it sit for 30 minutes. In addition to reacting with oxygen levels, bleaching powder poses fewer health hazards than other chemical substances like THMs.

Supplies needed: Include a 250 ml measuring flask, a weight box, a burette, a titration flask, a 100 ml graduated cylinder made of glazed tile, glass wool, bleaching powder, a solution of sodium thiosulfate (0.1 N Na2S2O3), several water samples, and a solution of starch.

• Quantity of Presence of Casein in Different Samples of Milk

Aim: To quantify the amount of casein present in various milk samples.

Theorem: Milk contains a protein called casein, which is most frequently seen as sodium caseinate. Milk turns sour when left out for a long time because the bacteria turn it into lactic acid. In acidic environments, milk casein begins to precipitate out.

Supplies needed: Beakers, funnels, conical flasks, 100 mL measuring cylinder, watch glass, Filter paper, 1% acetic acid, various milk samples, and a glass rod.

• Paper Chromatography

Aim: Employing paper chromatography to examine the ink components in black markers and pens.

Theorem: Complicated mixtures can be broken down into their component parts using chromatography. To create newer colours, ink makers combine numerous hues. Using paper chromatography, different substances can be separated by drawing them to alcohol or water.

Supplies needed: 100 mL beaker, a 500 mL beaker, two mini binder clips, two wooden splints, several black pens, and markers.

• Effect of Potassium Bisulphate as a Food Preservative

Aim: This project’s goal is to examine how potassium bisulfite performs as a food preservative in various scenarios.

Theorem: As a result of environmental conditions including temperature, time, and enzymes, certain food items go through natural alterations that render them inedible or decaying. By monitoring the content of potassium bisulphite (KHSO3) under various situations, food material can be efficiently preserved.

Supplies needed: Beaker, glass bottles, a balance, a peeler, a pestle, and a mortar, together with fresh fruits, a knife, potassium bisulphite, and sugar, are needed.

• Surface Chemistry Colloidal Solutions

Aim: To research the chemistry of colloidal solutions’ surfaces.

Theorem: Colloids are homogeneous mixtures with distinct phases. Particles that are equally spread across the continuous phase make up the dispersed phase. Some colloids display the Tyndall effect, which causes them to become translucent (Scattering of light by colloidal particles.). Gums are organic polysaccharides that are released by the stems of trees. This soluble material is hydrolyzed when heated with water, producing a variety of monosaccharides that result in a colloidal solution.

Supplies required: Two beakers (250 ml each) are needed, as well as a funnel, wire gauze, glass rod, a tripod-stand, a burner, filter papers, 100 ml of distilled water, and Arabic gum.
