The independent variable was the surface area. The dependent variable was the Alka Seltzer. The controlled variables were the amount of water, and the number of Alka Seltzer tablets. The data table for this experiment contains the results that prove how the different surface areas of an Alka Seltzer tablet affect the rate of reaction Purpose - Lab 6-b: Factors Affecting Reaction Rate. Purpose. Part 1. To test how the temperature of water (cold, warm, and hot) affects the rate of reaction at which an Alka Seltzer tablet dissolves. Part 2: Effect of Concentration. To test how the concentration of HCl (0.1M, 1.0M, 2.0M) affects the rate at which a piece of zinc metal will. In this experiment, you will study the effect that temperature and particle size have on the rate of a chemical reaction. Materials: Alka-Seltzer tablets four clean glasses stop watch or watch tap water (room temp, cold, hot) thermometer spoon vinegar measuring cup sandwich baggie Procedure: 1. Obtain three packets of Alka Seltzer tablets
Dependent Variable: Rate of reaction Control Variables: Number of Alka Seltzer Tablets, Exact Temperature of Water, Amount of water Part 2: Effect of Concentration If rate of reaction is related to the concentration of HCl (0.01M, 0.5M, 1.0M), the higher the concentration of HCl, the faster the piece of zinc metal will dissolve This reaction rate experiment explores the affects of surface area, temperature, and pressure on the rate of a chemical reaction. In this experiment, the reaction is between an Alka seltzer tablet (sodium bicarbonate + citric acid) and water. When an Alka seltzer tablet is placed in water, the H+ ions from citric acid react with the bicarbonate. We put three Alka Seltzer Tablets in three different temperature of water and measured the time it took for each to dissolve completely. By measuring the time and comparing the results, we would be able to determine whether temperature affects the rate of chemical reactions, if so, how it does so. We controlled certain variables
- in my experiment, the time Alka Seltzer tablet uses to dissolve in water decreases as the water becomes hotter and increase as the temperature becomes lower. Temperature affects the rate of chemical reaction; the higher temperature the reactants have, the higher the rate of chemical reaction will be; the lower temperature the reactants have, the lower the rate of chemical reaction will be Alka-Seltzer Lab Report but also how the temperature affects the rate of reaction (hot and cold). The purpose of the experiment is to learn what key factors affect the rate of reaction and what are the key characteristics of what happens during a chemical reaction when Alka-Seltzer in Glucose
temperature water. 4-piece tablet took 1 minute and 5 seconds to dissolve. Powder Alka Seltzer took an average of 44 seconds to dissolve. So it is much quicker if it is a form of power. Experiment 2 A whole Alka Seltzer dissolved on average 23.5 seconds in 80 degrees Celsius hot water. For 19 degree Celsius room temperature water, Alka Seltzer dissolved in average 1minute and 15 seconds Note: In this science project, you will investigate how water temperature affects the dissolving time of an Alka-Seltzer tablet. You will use a smartphone equipped with a sensor app to record the fizzing sound of the Alka-Seltzer reaction in water and measure the time it takes for one Alka-Seltzer tablet to react completely in water
Lab #18: Factors that Affect the Rate of Chemical Reactions This lab will focus on exploring these different factors and seeing how they affect the reaction of an alka-seltzer tablet. Alka Seltzer tablets contain solid sodium bicarbonate and citric acid. When dropped into water, sodium citrate, carbon dioxide, and water are formed: NaHCO 3. . When an Alka-Seltzer tablet is put into water, there is a reaction. The reaction, however, is . NOT. between the chemicals in the Alka-Seltzer . and the water
Q's 1 through 5 please. Factors Affecting Reaction Rates. Objective: To Identify factors that affect the rate of a chemical reaction; When Alka-Seltzer is dropped in water it starts fizzing due to rapid production of CO 2 gas. All of the chemical reactants are present in the Alka-Seltzer tablet; the water dissolves the reactants and facilitates the reaction the impact of temperature on the rate of the reaction. Students place seltzer tablets in water at different temperatures to observe the different reaction rates. This lesson can be extended to address parts of a reaction, energy of reactions, and other ways to affect the rate of a reaction. • CONTENT TOPIC THe effect of vinegar concentration on the dissolving rate of alka-seltzer tablets By: Emma Webster, Courtney Walker, Halle Glazebrook, and Kennadie Halliday 16 August 2016 Materials Research Question 4 150 mL beakers 150 mL of water 250 mL of vinegar Stop Watch Two Alka-Seltzer The experiment consisted of careful and fragile testing of Alka-Seltzer tablets and the reaction they posed to the water they were dipped or dropped in towards. The results showed a demonstrative aspect of rates in which the tablet dissolved, showing a pattern and use of graphing for the Alka-Seltzer's activity
Alka-Seltzer is a medical drug that works as a pain reliever and an antacid (antacids help neutralize stomach acidity, such as heartburn). The pain reliever used is aspirin and the antacid used is baking soda (sodium bicarbonate, NaHCO 3).To take the tablets, they should be fully dissolved in a glass of water For this lab you are expected to design a lab, which investigates the effect of a factor that changes the rate of reaction of Alka Seltzer in water. Preliminary Research • Do some background research of what Alka Seltzer is and make notes making sure that you record all the sources you used as it will be necessary to reference them in your lab In this experiment, we're going to learn how temperature affects the speed of chemical reactions. To do this, we'll be using the over-the-counter medication Alka Seltzer and studying its reaction.
The rate of the Alka-Seltzer reaction is dependent on both the rate at which the solids dissolve and the rate at which they react once in solution. This activity focuses on the chemical reaction for this experiment. You may wish to clarify for students that dissolving the Alka-Seltzer tablet is a physical change, rather than a chemical change (So, of course, reducing the temperature by 10 °C halves the reaction rate.) We'll test that rule in this lab by reacting Alka-Seltzer tablets with water at different temperatures. When an Alka-Seltzer tablet is dropped into water, it emits carbon dioxide as it dissolves and its components react . The pain reliever used is aspirin and the antacid used is baking soda, or sodium bicarbonate. To take the tablets, they're fully dissolved in water, where they famously undergo a chemical reaction that.
. The factors affecting the rates of reaction that were investigated in this lab were temperature (hot or cold water), concentration (amount of Alka-Seltzer or water added), and surface area (the surface area of the Alka-Seltzer). There was only one factor not investigated which was catalyst. 3. In the first trial, 15 mL of cold water and a 1. TEMPERATURE AND RATE OF REACTION ACTIVITY INTRODUCTION: Alka Seltzer in water produces carbon dioxide. It is the same reaction as vinegar and baking soda (sodium bicarbonate) because the Alka Seltzer has a chemical in it that makes water acidic like vinegar.

Factors that affect the speed of a reaction Every chemical reaction is subject to a series of factors, which cause the speed of the same to pass quickly or slowly. We find reactions that happen in seconds, like explosions, and others that take a little longer, such as the oxidation of an iron rod put out in the open TOPIC 5. LAB ACTIVITY 3 The Effect of Concentration Changes on Reaction Rate The course of the reaction between sodium persulphate (Na2S2O8) and potassium iodide (KI) solutions can be followed by adding small quantities of starch and sodium thiosulphate (Na2S2 O3) to the reaction mixture
Chemical Reactions proceeds at different rates. The difference in rates of reaction is caused by several factors such as Concentration of Reactants, Temperat.. In your lab you changed the concentration of one of your reactants (water) by mixing it with alcohol, which is NOT a reactant for this chemical reaction. The alcohol made it so that water and alka-seltzer did not collide with one another as often. The alcohol blocked some of the water from the alka-seltzer Also, an excess of one reactant can cause the overall reaction to takeplace at a faster rate. Once the limiting reactant is used up, the reaction will stop.Alka Seltzer contains aspirin (acetylsalicylic acid), citric acid, and NaHCO 3 as the activeingredients. This medication is designed to be taken by dissolving it in water beforeingesting in Alka Seltzer tablets can be determined by the method of eudiometry (10). In +the experiment described in this article, an alternative to the work of Peck et al.
