The document analyzes the contents of various cold drinks available in the market. Experiments were conducted to test for the presence of glucose, alcohol, carbon dioxide and acidity. Glucose was detected using Benedict's solution which turned reddish upon heating. Carbonation was observed by the limewater turning milky as carbon dioxide dissolved in it. Alcohol presence was shown by a yellow precipitate forming when iodine, potassium iodide and sodium hydroxide were added. The drinks' pH showed them to be acidic, with Coca Cola having the lowest pH. While cold drinks provide refreshment, they also have disadvantages like potential for weight gain, harming bones and aiding corrosion.
