surface area vs rate of time
In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches. This experiment would benefit society because it informs the society the better way of consuming medicine or alka seltzer in order to see faster effect in the body.
Aim: To investigate the breaking of the alka seltzer into larger surface area (½ and ¼) affects the time it dissolves.
Hypothesis: The more alka seltzer is broken, it dissolves faster in water and the less it’s broken, slower it dissolves in water.
- 9 alka seltzer
- Room temperature water
- 3 Glass cup or clear plastic cup
- Measuring cup
Safety risks and precautions:
Spilling water on electrical appliances, getting a cut with a knife or broken glass
Make sure to proceed this experiment on a table far away from electricity or any electrical appliances.
Be careful when cutting or breaking the alka seltzers.
Be careful not to knock over the…
Alka-Seltzer is a medication used to alleviate ailments such as heartburn and acid indigestion1. The ingredients that the tablet is made up of helps explain the name of the medication, the sodium bicarbonate is used to balance stomach acid, help spread the aspirin which allows the speed of absorption to increase, and reacts with citric sodium which produces carbon dioxide2. One initial observation of the Alka-Seltzer tablet and water is that when the tablet was dropped into the…
ideal ratio of Alka-Seltzer to water that will produce the longest canister flight time? In the first experiment, we asked, what amount of water will produce the longest canister flight time? In the second experiment, the question was, what amount of Alka-Seltzer will produce the longest canister flight time? The main reason this lab was split into two parts was because there can only be one independent variable per lab, therefore, the water and Alka-Seltzer testing had to be done separately. In…
This experiment was divided into two parts: one part was to observe the properties of a single Alka Seltzer tablet and the second part was to find the percentage of CO2.
In the first part of the experiment, the visible properties of Alka Seltzer were observed and recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate.
Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking…
I will be conducting focuses on how fast one tablet of Alka seltzer can dissolve in various temperatures of water. The core of this procedure is to determine the impact that temperature has on how fast something dissolves. My hypothesis for this experiment would be that the Alka Seltzer that dissolves the fastest would be the one that was placed in the water with the highest temperature. There will be controlled and manipulated variables explained throughout the experiment. The two main things…
The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster.
Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931. In 2006,…
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…

Good Will in Price Bidding. Sometimes, a bidder on a work contract may bid lower than what would maximize his/her profit from the contract and the reason for that is to create goodwill (to increase expected future business from the buyer). How would you value the goodwill that is obtained in this way?

Graph 1 displays the reaction time (in minutes) of how long it took for the Alka-Seltzer tablet to completely dissolve per trial. Graph 2 displays the averages of the reaction time which showed the higher the water temperature is, the faster the reaction time would be. At 65⁰C the average time for the Alka-Seltzer to completely dissolve was 1 minute 4 seconds followed by 1 minute 20 seconds at 35⁰C and ending with the highest average at 2 minutes 1 second (1.61).
The main objective of this lab was to collect 〖Co〗_2 gases that were given off by the Alka-Seltzer tablets and to identify experimental masses. The volume of gas was 724 liters, or 723.86 cm and the experimental mass was .0894 grams. A balance scale was used before and after the reaction to record the change in overall mass. First, using the scale, the flask, balloon, and Alka-Setlzer tablets were measured, 259.4 ±.05 Grams were found. What created the “〖Co〗_2 gases to be trapped” were the…
