INTRODUCTION It has been observed that chemical reactions occur at different rates. But, what causes the rates to change? One of the most effective ways to find the answer to that question is through experiments. It has been learned through experimentation that the concentration of a chemical and the temperature can affect the rate of the reaction (Taylor and Mortimer 2002). The formula of Alka-Seltzer is C16H17NaO14. With its large amount of hydrogen ions, it’s the perfect combination to use. Heat has to be absorbed in order to break hydrogen bonds in a chemical reaction. Since Alka-Seltzer has 17 hydrogen molecules, it would take a lot more heat to break the bonds quickly. The bonds could break at lower temperatures, it would just take longer. This research poses the question: does the temperature actually affect the rate of a chemical reaction? Alka-Seltzer has chemical energy: the potential energy …show more content…

The reaction rate changes based on temperature, so if the cold temperature or hot temperature isn’t the same for all of the trials, the reaction time won’t be either. If the temperatures are too similar, like the cold and room temperature in all three trials, there isn’t a constant temperature gap to accurately see the reaction time difference. The temperature difference between the cold, room temperature, and hot water for each beaker should be constant for all trials. The timer could also be a potential error. The time needs to be started and stopped at the same point for all of the tablets, so human error could have occurred. Also, the tablets could pose an error if they aren’t the same size or broken. The tablets used should not be broken, and they should be weighed before each

Hand Warm Lab Report

After seeing this data the two most effective look chemical at resisting energy was CaCl2 and LiCl. So we looked at the price of both of this chemical CaCl2 cost 6.55$ per 500g and LiCl cost 32.75$ per 500g because CaCl2 was substantially cheaper we decide to chose it to use in own hand warmer. We calculated that it would take 22g of CaCl2 to create a 20oC increase in temperature of 100ml of water. Some sources of error in this lab, would be heat escape from not be able to replace the lid of the calorement went adding chemical into it, inaccuracies in the balance, and not waiting of the proper time to recode the

A Brief Note On Alka Seltzer Solution

204 Words | 1 Pages

A buffer solution minimises change in PH of a solution when small amounts of acid or alkali are added to the solution, with an an acidic buffer solutions maintaining a PH<7 (ChemGuide, 2017). It works through an equilibrium, so if the concentration of H+ or OH- are changed, equilibrium will shift to oppose this change and return solution PH to original value. The Alka Seltzer mixture contains an excess amount of the bicarbonate ion which is vital for the buffering action taking place within the solution. This is because the excess bicarbonate ion present, allows the solution to act as a buffer as it’s able to react with small quantities of acids and bases added to the solution, therefore resisting a change in PH by neutralising them.

Alka-Seltzer Experiment

853 Words | 4 Pages

Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.

The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with

Introduction 1.1 Aim: To determine the kinetic parameters, Vmax and Km, of the alkaline phosphatase enzyme through the determination of the optimum pH and temperature. 1.2 Theory and Principles (General Background): Enzymes are highly specific protein catalysts that are utilised in chemical reactions in biological systems.1 Enzymes, being catalysts, decrease the activation energy required to convert substrates to products. They do this by attaching to the substrate to form an intermediate; the substrate binds to the active site of the enzyme. Then, another or the same enzyme reacts with the intermediate to form the final product.2 The rate of enzyme-catalysed reactions is influenced by different environmental conditions, such as: concentration

Each beverage has the ability to attract people from different age groups, young to old. Over the years of researching energy drinks, psychologist have found that it is true that young people are more likely to consume energy drinks then people in their forty’s. Research has proven this to be true based of it’s characteristics based off of its taste, which are usually combine with fruitiness and sweetness. Also by its ability to deliver quicker doses of caffeine to the body, this appeals more children and teens. Yet, coffee is considered bitter and can be used to make medicines work faster.
