experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate and

Rate of Reaction Experiment Introduction : in this term in chemistry class I was learning about rate of reaction. As defined by the Britannica encyclopedia‚ a chemical reaction is a process where one or more substances (reactants) are converted to one or more different products because of the rearrangement of atoms of the reactants. For the reaction to occur‚ the particles must collide with each other and in order to succeed there must be enough energy for the collision because a collision with little

An investigation in to the rate of reaction Plan: I am going to investigate the rate of reaction. The reaction I will be using is: Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide. CaCO3 + 2HCl ---- CaCl +H2O + CO2 Measurements and Variables: The variables I have chosen to change is strength of the hydrochloric acid which will be 1 mole‚ 0.7 mole‚ 0.5 mole‚ 0.3 mole and 0.1 mole some variable I will not be using are temperature‚ mass‚ density. The measurements

An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in

increase the concentration of NaOH from 0.5M to 1M‚ then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL of Acetic Acid at 50%

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

Determination of the Concentration of Acetic Acid in Vinegar Lab Exercise 4 CHEM 1106 9/19/12 Purpose: Standardize a sodium hydroxide solution using a primary standard acid. Determine the molarity and the percent by mass of acetic acid in vinegar by titration with the standardized sodium hydroxide solution. Introduction: Vinegar is a dilute solution containing acetic acid. Since vinegar has a low pH‚ it can be titrated with a base. Titration is a method used in order to ascertain

neutralization reaction of ethanoic acid and sodium hydrogen carbonate Cristina Li 17th April 2017 Introduction The hypothesis is the balloon will be bigger and bigger with the increase of vinegar. The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction. Sodium hydrogen carbonate (baking soda)

investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they have
