Investigating Rate of Reaction Aim I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant in order to carry out a detailed investigation. Formulae ======== The formula for the chemical reaction is: ========================================= CaCO3(s) + 2HCC(l) CaCl2 (aq) + H2O(l) + CO2 ============================================ I can measure the rate of reaction between the two substances using this formula. Rate of Reaction = Change in Concentration ------------------------------------------ Time Taken for Reaction A chemical reaction is the name given to a substance when it changes and becomes a completely new substance. It is difficult to reverse. It happens when particles make effective collisions with sufficient energy. Apparatus ========= Spatula ------- Conical Flask ------------- Burette Stand + Clamps Measuring Cylinder Safety Goggles Beaker Thermometer Stopwatch Kettle + water Small Funnel Delivery Tube + Bung I have chosen to use a measuring cylinder to make my experiment as accurate as I possibly can. I will be wearing the provided safety goggles at all times to protect my eyes, as hydrochloric acid is an irritant that may prove dangerous if it makes contact with the eyes. Theory The following theories will help me decide which variable I will change in my experiment to investigate the rate of reaction using calcium carbonate and hydrochloric acid. Temperature - Collision Theory ============================== The diagram shows particles that are not moving quickly. This means that the chance of these particles colliding and causing a chemical reaction is rather low. The temperature is obviously low too, as the particles have little energy to move quickly. However, if heat were added, the particles would have more energy and move quicker and have a better chance of colliding. This diagram shows particles that are moving quickly. This means... ... middle of paper ... ...respond with my prediction and back it up. As the temperature increases, so does the rate of reaction. If I were to repeat the experiment again, I would work under strict environment, such as in a closed room with no winds or temperature changes. I would also try and use more accurate ways of reading the temperature and keeping the temperature constant, such as by using a water bath. Doing this would possibly make my results even more accurate. I would also try and make my timing even stricter, possibly using a smaller time interval such as 10 seconds instead of 15, to get slightly more accurate results. I may also use a larger range of acids. I only tried the 1 molar acid, but if I were to repeat the experiment again, I would perhaps use 3 and 4 molar acids and test them under high temperatures. I would like to investigate in future the effect of catalysts and surface area on the rate of reaction, to be more conclusive on the subject and widen my knowledge. All in all, my experiment was a success. Everything went well, and I believe that the techniques and methods I used were accurate and sufficient enough to provide me with a sound set of conclusive results.
Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips
The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.

Investigate how the concentration of hydrochloric acid effects the rate at which it reacts with calcium carbonate
The Effect of Temperature on the Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.

from 10cm to 50cm to make it easier to see the difference in a graph.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.
Rate of Reaction Between Marble Chips and Hydrochloric Acid. The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) is used. There are many variables that affect the rate of this reaction such as the following. 1.
The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
My aim in this piece of work is to see the effect of temperature on the rate of a reaction in a solution of hydrochloric acid containing sodium thiosulphate.
Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
