Methods For this experiment, 100 ml of orange juice, and 100ml of water were measured out. The temperatures of the liquids were the same. Next, the ph levels of both liquids were measured. One Alka seltzer was dropped in the water and one in the juice, and timed how long it took to dissolve.…
Which temperature (hot, cold, room temperature) caused the reaction to proceed the fastest? Why? How does this relate to the diffusion experiment? The hot water caused the Alka Seltzer to proceed the fastest because the higher heat sped up the chemical reaction. This experiment relates to the diffusion experiment because the higher temperature in both experiments produced the fastest results.…
It was identified as more alka seltzer is broken it is dissolved faster. The experiment was to put alka seltzers that is broken into ½, ¼ and unbroken ones into 125ml, 21 degrees Celsius (room temperature) water. The trend occurred because the decrease of the size of the particles which increase the rate of reaction because the surface area of reactant (alka seltzer) has been increased. A larger surface area has increasing target of colliding with the molecules, the bigger the target is, it is easier to hit the water molecules. This is why the more alka seltzer is broken, it dissolved the…
Observations: 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.…
The Effect of Temperatures on Rate of Reaction of Alka-Seltzer Introduction: A. Background This particular experiment consists of a purpose of finding out the effect of various temperatures on the rate of reaction of the Alka-Seltzer tablets. Alka-Seltzer is a medical drug that acts as a pain reliever or an antacid, which helps neutralize stomach acidity, such as heartburn. Alka-Seltzer is a form of a baking soda which is also known as sodium bicarbonate, (NaHCO₃). When sodium bicarbonate (NaHCO₃) comes in contact with water (H2O), the compound dissociates into two different ions: sodium (Na+) and bicarbonate (HCO₃-) ions.…
In summary, on 05/03/16 at 1742 hours while I was patrolling the area of 1500 S 50th Ave. I observed a parked vehicle (08' black Pontiac IL P312325) with three (3) male subjects inside drinking bottles of Modelo Beer. I made contact with the males subjects while they were removing a twelve case of Modelo Beer from the vehicle. I observed eleven (11) empty bottle of Modelo beer and one (1) bottle sealed inside the case. I also observed a Modelo beer bottle with the seal broken in the center console of the vehicle.…
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.…
Mold is fungi that are found outdoors and inside homes. Molds grows exceptionally well on paper products and in moist dark environments. Nevertheless, mold is found in every environment, including dry conditions and reproduce year round. Areas in which mold are found include greenhouses, saunas, farms, mills, construction areas, basements and showers. According to the Center of Disease Control (CDC) mold thrives on three conditions.…
This experiment proved that as temperatures cooled the reaction time slowed down (http://www.ebi.ac.uk/interpro/potm/2004_9/Page1.htm). During the experience I initially put the thermometer on the bottom of the test tube which gave me the wrong temperature, so I had to redo the the test. Another error was during the reaction the liquid overflowed the sides of the test tube and it maid it hard to read the results. I would recommend that. Bibliography:…
In this lab, the main question is, what is 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 the canister, the Alka Seltzer contains Citric Acid and Sodium Bicarbonate.…
The faster motion means that the solvent molecules collide with the solute with a higher frequency and the collisions occur with more force. Both components help to increase the rate at which the solute dissolves. A change of temperature does not only affect the rate of dissolving, but it also affects the amount of solute that…
Dr Pepper is a well known drink across the world. For me, it is the most delicious soft drink in the business. Dr Pepper has many secrets in its can. Who wouldn’t want to crack open a can of Dr Pepper and see what it really is. Dr Pepper was brought into the world in 1885 in Waco,Texas.…
Temperature and the time of the bubbles are related to each other because the temperature can affect the molecules that is in the soda/liquid which affects the time it takes to get flat. For example, ThoughtCo. found that bubbles pop more quickly during the warmer temperature. If the temperature decreases, then the time of the bubble’s lifespan will increase because in the colder temperature, carbon dioxide has less room to move and escape and the more carbon dioxide that is in the soda, the more fizz that the soda/liquid will…
The theoretical concepts that underlie the Hot Ice experiment involve a supercooled, supersaturated aqueous solution becoming a solid. When a liquid is cooled beyond its freezing point but remains liquid is known as supercooling or undercooling, and being supersaturated occurs when the solutes in a solution exceed the saturation point. The sodium acetate in a supercooled state will rapidly change into a solid with the addition of physical energy or a nucleation site. During the transformation of the liquid supercooled solution into solid crystalline formation produces heat in an exothermic reaction, hence the name hot ice.…
Investigative Question Does sugar or salt effect the freezing point and period of time that water takes to freeze? Hypothesis If you add either sugar or salt to water it will affect the freezing point of the water and will therefor take longer to freeze. Aim…
