3. WHAT ARE SOFT DRINKS ? ? ? ? ? ? ? Soft drink is also known as club soda, soda water, sparkling water, carbonated water & fizzy water. It is water into which carbon di oxide gas under pressure has been dissolve, a process that cause the water to become effervescent. and the process is called carbonation. Soft drinks have become so much a part of modern living, especially in major cities around the world. It particularly appeals to the younger generation who drinks soft drinks in place of water 11/05/2014 SOFT DRINKS …show more content…
EFFECT OF CAFFEINE Caffeine is an addictive drug that enhances the flavor of soft drinks. It artificially stimulates the nervous system and increases the heart rate. Excessive caffeine consumption is linked to cancers of the bladder and stomach and raised blood pressure. It may even contribute to birth defects in babies. Excessive urination and other health problems. 11/05/2014 SOFT DRINKS & ITS HARMFUL EFFECTS 8

10. OBESITY: Drinking a single 330 ml can a day of sugary drinks translates to more than 453.592 gm of weight gain every month. The relationship between soft drink consumption and body weight is so strong that is each additional can of soft drink consumed, the risk of obesity increases 1.6 times. Sugar-sweetened beverages are linked to more than 180,000 obesity related deaths a year. 11/05/2014 SOFT DRINKS & ITS HARMFUL EFFECTS 10

Dehydration Both caffeine and sugar cause dehydration. Caffeine is a diuretic and causes an increase in urine volume High concentration of sugar is drawing off water because your kidneys try to expel the excess sugar out of the blood. When you drink a caffeinated soft drink to quench your thirst, you will actually become thirstier 11/05/2014 SOFT DRINKS & ITS HARMFUL EFFECTS 18
19. KIDNEY FAILURE: Drinking large amounts of soft drinks containing phosphoric acid may be especially harmful. Having poor kidney function can lead to unusually high levels of phosphorous in your blood that lower calcium levels, increasing your risk of bone disease and brittle bones. That cola beverages can increase the risk of kidney problems, more so than non-cola sodas. Large quantities of cola result in enhanced kidney stone formation 11/05/2014 SOFT DRINKS & ITS HARMFUL EFFECTS 19
20. TEST FOR CARBON DIOXIDE 11/05/2014 SOFT DRINKS & ITS HARMFUL EFFECTS 20 Take bottles of soft drinks. As soon as the bottles were opened, one by one the sample was passed through lime water. The lime water turned milky. Conclusion: All the soft drinks contain dissolved carbon dioxide in water. The carbon dioxide dissolves in water to form carbonic acid, which is responsible for its tangy taste. CHEMICAL REACTION: Ca(OH) 2 + CO 2 ----- CaCO3 + H2 O Sr. No. Name of the drink Time taken (sec.) Conclusion 1 Coca Cola 26.5 CO2 is present 2 Sprite 21 CO2 is present 3 Limca 35 CO2 is present 4 Fanta
