It is widely distributed in nature in juices, seeds and also in flowers of many plants. The molecular formula of sucrose is C12H22O It is produced by a mixture of glucose and free dose.

It is non-reducing in nature whereas glucose is reducing. Cold drinks are a bit acidic in nature and their acidity can be measured by finding their pH value. The pH values also depend upon the acidic contents such as citric acid and phosphoric acid. The change in the color of pH paper was noticed and was compared with the standard pH scale. Serial No.

As soon as the bottles were opened, one by one the sample was passed through lime water. The lime water turned milky. Name of Drinks Time Taken Sec. Conclusion 1 Coco-Cola Glucose is a reducing sugar acid. Hence all the drinks contain glucose. The test tube was heated for few seconds. Formation of reddish color confirms the presence of glucose in cold drinks.

The test tube was heated in a water bath for 10 minutes. Appearance of brown precipitate confirms the presence of glucose in cold drinks. Hence all the cold drinks contain glucose. All the soft drinks contain phosphate ions which are detected by the presence of phosphate when canary yellow obtained. Samples of each brand of cold drinks are taken in sample test tube and iodine followed by potassium iodide and sodium hydroxide NaOH solution is added to each test tube. Then the test tube are heated in hot water bath for 30 minutes yellow colored precipitate confirmed the presence of alcohol in cold drinks All the Brands of Cold Drinks Contain Alcohol.

Black colored residue left confirms the presence of sucrose in cold drinks. All the brands of cold drinks contain sucrose. But amount of sucrose varies in each brand of drink. Fanta contained highest amount of sucrose. Coca cola 2. Below is the list of Chemistry Projects on Electrochemistry:. Below is the list of Chemistry Projects on Surface Chemistry:. Below is the list of Chemistry Projects on Chemical Kinetics:. Below is the list of Chemistry Projects on Chemical Solutions:.

Below is the list of Chemistry Projects on Solid State:. Below is the list of Chemistry Projects on Polymers:. 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.

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 ml. 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.

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. 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.

Apart from these two popular choices for the chemistry project for class 12 students, you can decide and design a project based on your own choices and depending on the available resources. Given below is the list of top ideas that you can choose to prepare your chemistry project for class 12 CBSE easily:.

We hope that we have provided you with every little detail you wanted to prepare for your chemistry project for class
