TITLE:
INTRODUCTION:
Alka-Seltzer is used to reduce pain, inflammation, heartburn etc. It is an antacid. When it is dissolved in water, it produces carbon dioxide filled air bubbles. It is represented by CO2.(1) Alka-Seltzer consists of citric acid and aspirin. Bicarbonates are formed when the tablet is dissolved. When it is mixed with citric acid, then the acid reacts with bicarbonates and water, carbon dioxide are formed.(1)
When Carbon and oxygen bonded, then carbon dioxide gas is produced.(2) It is colorless, odorless gas. when fossil fuels are burned, this gas is produced. It increases the effect of global warming. (2).Carbon dioxide consists of one covalent bond. It tastes like a faint acid. It is incombustible.(3)

11. Grinding twist with the pestle.
METHOD FOR PART 2: All the materials required to do this experiment are gathered. Take a Beaker and add 70ml of water into it. Make sure to balance the scale. Cut a wax paper with 5cm*5cm.Crush the tablet with the hawy hand wike grinding twist with the pestle 9x. Sit wax paper, beaker with crushed tablet on a balance scale and record the initial mass. Put the crushed tablet into the water and start timing as soon as possible. Keep mobile phone near the scale and catch another mobile phone. Click on slow motion camera for about one minute 40 seconds to note the mass and time. Wear a pair of gloves, take crushed tablet powder and click on camera (slow motion). Drop this crushed tablet into beaker and start the camera. For every 10 seconds, calculate mass and time in the recording.

60 sec to 70 sec mass is increased and then decreases till 90 sec.From 100sec to 140 sec mass is decreased.
DISCUSSION AND CONCLUSION:
The reaction of alka-seltzer is increased by increasing the surface to volume ratio.
Hypothesis states that the tablet reaction is related to increase the surface to volume ratio.
Surface to volume ratio increased by crushing the alka seltzer tablet. Take a beaker with water and dissolve it. The time taken to dissolve the crushed tablet is less when compared to the time taken to dissolve for full direct tablet. This states that the rate of reaction is increased when the surface to volume ratio is increased.
Errors may occur in calculating time and mass. Take necessary steps to avoid these errors. The experiment is conducted for completely crushed tablet but not for partially crushed tablet.
Hypothesis is supported by stating that rate of reaction is related to the surface to volume ratio. Where with increase in surface to volume ratio, the rate of reaction is
