Chemistry is a fascinating branch of science with huge career possibilities. CBSE’s 12th-grade curriculum includes investigatory projects in chemistry that allow students to grasp the basic theories. You are looking for help with your 12th-class project? This blog will provide you with all the details you need to prepare your chemistry project.
Popular Chemistry Project Class 12
Your time is limited and you may not have the time to complete your board exams. It is recommended to prepare your Chemistry Project quickly and clearly. Here’s a list of 12 most popular chemistry projects.
The process of attaching molecules to a surface
Adsorption is a process where a substance is transferred from fluid bulk onto a solid substrate by means of the forces created by chemical bonds. This is where liquid and gaseous particles bond to a solid surface, called Adsorbate. They form molecular adsorbate films. Adsorption can be reversed and is most commonly described at equilibrium. This describes the quantity of substance attached on the surface to the fluid and its concentration. This concept is very popular among students in chemistry class 12.
Synthesis Of Aspirin
Aspirin, a popular Chemistry project for class 12, is one of the most interesting. This is a common term for a compound called acetylsalicylic Acid. This is commonly used in everyday life as a painkiller. Salicylic acid is the natural product that is extracted from bark extracts from the Willow family of plants. It was previously used to treat fever and headaches. It is irritating and bitter for the stomach so the aspirin form is used.
Project Details
Below are some chemistry projects that class 12th students can do.
Bleaching Powder is used to sterilize water
Aim: This experiment is designed to determine how much bleaching powder is required to sterilize or purify different water samples.
Theory: Bleaching powder or Calcium Hypochlorite [Ca (ClO),] can be used to disinfect drinking waters. The bleaching powder is added to 2 litres water with 5 drops. After that, it sits for 30 minutes before being made safe for drinking. Bleaching powder is also less likely to cause decay than other chemical compounds, such as THMs.
Requirements: 250ml measuring glass, weight box and Burette. 100ml graduated circular glazed tile with a glazed tile.
Analyse of Fertilizer
Aim of the experiment: This experiment examines water’s refractive content using a moving microscope.
Theory: Refraction occurs when light travels through transparent media in a direction that changes. By calculating the distance of light between two mediums, a refractive indicator can be calculated.
Requirements: A travel microscope, a beaker, a piece of paper, a coin and a pen.
Guava Fruits and Ripening Stages: Oxalate Ions
Our aim: To analyse the presence of Oxalate Ions in Guava Fruit and to identify different stages of its ripening.
Theory: The body produces carboxylic acids by converting Vitamin C to oxalate. Hyperaluria (kidney stone) can result from excess oxalate found in the urine.
Requirements: 100ml. Measurement flask burette.
Potassium Bisulphate is a food preservative
This project aims to examine the effects of Potassium bisulfite on food preservation under various conditions.
Theory: Food materials go through natural changes. These include temperature, time and enzymes. This causes them to become inconsumable or decay. By ensuring that the concentration of food material is maintained under various conditions, potassium bisulphite can be used (KHSO3).
To complete the task, one will need a beaker, several glass bottles, a scale, a peeler, a mortar and pestle, several fresh fruits, a knife, potassium bisulphite, and sugar.
Different milk samples have different amounts of casein.
The aim is to analyze the amount of casein present in various milk samples.
Theory: Calcium caseinate, one of the most prevalent forms of caseins in milk, is the most commonly found. The bacteria in milk can turn it into lactic acid if it is not kept away for long periods of time.
Acidic conditions cause the milk casein to start precipitating.
To conduct a milk analysis, you will need a conical flask, funnel, beakers, a 100 mL measuring cylinder, watch glass, filter paper, 1% acetic acid, various milk samples, and a glass rod.
Extracting essential oils from Ajwain and Illaichi, Cardamom, Saunf and Saunf.
Aim: To extract essential oils from Ajwain (Carum), Illaichi(Cardamom), Saunf, and Saunf.
Theory: Essential oils impart a pleasant aroma and can be used to flavor foods. They are complex mixtures that can be used for medical and insecticide purposes. They are most concentrated in flowers and seeds. However, steam distillation can extract them from plants which decreases the risk to essential oils vaporization.
To conduct a laboratory experiment, the following items are needed: a 500 mL round bottom flask, a conical flask, a copper steam generator, a condenser, glass tubes, an iron stand, a sand bath, a separatory funnel, tripod stands, burners, carum (ajwain), petroleum ether at a temperature of 60-80 degrees Celsius, and aniseed (saunf).
Surface Chemistry Colloidal Solutions
Our goal is to investigate the surface chemistry in colloidal solutions.
Theory: Colloids consist of homogenous solutions which contain distinct phases. The dispersed Phase is composed of particles that have been evenly distributed in a continuous phase. Some colloids are translucent due to the Tyndall Effect (Scattering Light by Colloidal Particles). Natural polysaccharides are gums, which are naturally secreted from stems of trees. The soluble substance reacts with water to hydrolyze it and gives rise to several monosaccharides. A colloidal solution is formed.
Two 250 ml beakers are required. 50 ml. ), Filter papers, Arabic gum 4.5 g, and 100 ml.
Paper Chromatography
The aim is to analyze ink components of black markers/pens using paper-chromatography.
Theory: Chromatography separates components from complex mixtures. To make new colours, ink manufacturers mix different colours. Paper chromatography allows you to separate ingredients by drawing them to alcohol and water.
Requirements : 100 mL Beaker, 500mL Beaker, 90% Isopropyl Alcohol (2), Mini Binder Clips (2), Wooden Spilts, Different Black Pens and markers
For cancer therapy, nano-gold
Aim: To investigate the possibility of using nano-gold to treat cancer.
Theory: Nano-gold particles are used to absorb infrared light and kill a tumor. It’s a little challenging, as the light should not damage healthy tissues.
Necessities include a vial containing nano-gold particles suspended in a red, pink, and blue solution, a vial of yellow-tinted water, a flask of water with a red, pink, and blue hue, LED torches, a magnet board from Seeing Scale, and a red theatrical gel.
The Solar Cell Turns on Electrolyte
Study of how electrolytes or other objects can affect the output energy from a solar cell.
Theory: Solar panels produce more energy if the materials are well blended. This experiment shows how different substances and objects can have an impact on the output energy of solar cells.
Requirements: 10ml vinegar, 6g titanium dioxide, dishwashing soap, TiO2 solution and berries.
