An Investigation of the Effect of Concentration Change On the Rate of the Reaction Between Magnesium and Hydrochloric Acid.

Extracts from this document...

Introduction

An investigation of the effect of concentration change on the rate of the reaction between magnesium and hydrochloric acid. Title The title of this piece of coursework is 'An investigation of the effect of concentration change on the rate of the reaction between magnesium and hydrochloric acid'. Aim I am going to investigate the relationship between the concentration rate of Hydrochloric acid and Magnesium reaction. Summary In this experiment, I will us different concentration rate of hydrochloric acid to react with magnesium and discover the time it takes to complete the reaction. I will also use three states of magnesium. Ribbon turning and powder, to see if there is any influence on the timing if different states of magnesium are used. I will take a few measurements during the experiment: 1. How long it takes to release a certain amount of gases? 2. What is the maximum amount of gas produced in 7 minutes? 3. Compare the different of reaction rate of 3 states of magnesium? Procedure I have to set the quantity of the amount of magnesium and the volume of hydrochloric acid, so I have done a TEST RUN before I do the practical test. ...read more.

Apparatus list 1. Magnesium ( ribbon, turning, powder ) 2. Hydrochloric acid 3. Water 4. Balance 5. Scissors 6. Micro test tube 7. Side-arm test tube 8. Measuring cylinder ( 10 ml and 250 ml ) 9. Box ( to contain water ) Variables 1. Concentration Increasing the concentration of reactants increases the rate of a reaction. This is because there are more particles in the same volume so more collisions are possible every second 2. Temperature Temperature will also influence the result of the experiment. This is because the temperature (heat) gives energy to the chemicals. At the higher temperature, the reactant particles move faster and collide more often and more violently. 3. Surface area The surface area of the chemicals will also change the result of the test. Breaking up the chemical into small pieces increase the reaction rate because the increasing surface area will increase the number of particles of the chemical in contact with other reactant in the solution. 4. Catalyst Catalyst increases the number of collision; it works by giving a platform for the reacting particles to stick to, so that they can collide each other easier. ...read more.
