Alka Seltzer Experiment

In conclusion, the liquid that dissolved the alka seltzer that fastest was water. The hypothesis for this experiment, was supported by the data that was collected. The average amount of time over the two trial experiment for the water beat the Minute-Maid Apple Juice by 21.5 seconds and the Sprite by 22 seconds. This may be because Alka-Seltzer contains citric acid and sodium bicarbonate (baking soda). These makes a reaction when dropped into the water and starts to create fizzing. The reaction to…

Method Experiment Report Student Name: Canyu Yu (Celine) Student Number: 1004145702 Experiment Title Effect of Surface Area on the Dissolution Rate Hypothesis The larger the surface area of Alka Seltzer tablets are, the faster the Alka Seltzer tablets will dissolve. The smaller the surface area of Alka Seltzer tablets are, the slower the Alka Seltzer tablets will dissolve. Methods (Please write in paragraph form – Marks deducted for point form) In the Alka Seltzer experiment, we…

case for the categories as follows: mass of beaker and liquid, Mass of Alka-Seltzer, and mass of contents in the beaker after the reactions completed. The two sections in this table that required math was total mass of content in the beaker before reactions and mass of CO2 produced. To find the total mass of contents in the beaker before the reaction began we added the Mass of the beaker and liquid plus the mass of the Alka-Seltzer tablet. Sample can be seen of this below in the Data section. To…

Alka Seltzer Lab Results

In this experiment, I will test the effect of temperature on reaction time for Alka-Seltzer dissolving tablets. Experiment one uses room temperature water, experiment two, hot water, and experiment three, ice water. In order to determine the effect of the water temperature, I will need to record the time it takes for the Alka-Seltzer to dissolve completely. Room Temperature Water: Fill a clear glass with exactly 8 oz. of room temperature Use a thermometer to read and document the temperature of the…

Alka-Seltzer Tablet

Safety: Be careful not to lean over the rocket. Eye protection should be worn during this experiment How do I start? Add approximately 1cm of water (between 1/4 and 1/3 full). Quickly place half of an Alka-Seltzer tablet in the film canister and fit the lid on the canister, making sure the seal is tight. Turn the canister upside-down on a flat surface. Stand back! How does it work? When an Alka-Seltzer tablet is dropped in water, the solid citric acid and baking soda (sodium bicarbonate) inside the…

Alka Seltzer Lab Report

what a relief it is!” Alka Seltzer, a common reliever of minor heartburn and indigestion pains, comes in the form of a tablet and contains anhydrous citric acid and sodium bicarbonate. When Alka-Seltzer tablets are dissolved in water, bicarbonate forms from the sodium bicarbonate. In turn, this reacts with hydrogen from the citric acid to form water and carbon dioxide gas. In this experiment, my group determined the most effective and speediest way to dissolve an Alka Seltzer tablet. There were…

being created! So we conclude with this the Lava Lamp consisted of two insoluble solutions. In this experiment, we attempted to use water and oil to imitate a real-life lava lamp. The liquid that is denser will end up sinking to the bottom of the experiment bottle while the other molecules rest on the top. We found out that the water sank to the bottom, leaving the oil at the top of the experiment bottle since the water is much denser than the oil is. A real lava lamp would contain a light bulb…

Lab 2 Some Factors Affect Reaction Rate Essay

Bingying Jiang CHM 152ll April 25, 2013 Some Factors that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * ƒ nature of reactants - particle size * ƒ temperature * ƒ catalysts According to the collision theory, the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions, the…
