The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
Aim To investigate if the temperature of hydrochloric acid will affect
the rate of reaction between hydrochloric acid and magnesium.
Magnesium Ribbon + Hydrochloric Acid → Magnesium Chloride + Hydrogen
Mg + 2HCl → MgCl² + H²
Hypothesis I think that as the temperature of the hydrochloric acid
increases so will the rates of reaction. I think this because of the
Collision theory. These theory states that particles, when heated have
more energy, and with this higher amount of energy the particles will
be moving at a higher rate with more force, when these particles
collide a reaction occurs, therefore increasing the heat increases the
rate of reaction.
Apparatus Pyrex Beaker Gauze Tripod Bunsen Burner Stopwatch
Thermometer Measuring Cylinder Experimented Materials i.e. HCl and Mg
Method The equipment was examined to ensure that it was sterile and in
working order. Then 50ml of hydrochloric acid was measured out in a
measuring cylinder. This was then poured into a clean Pyrex glass
beaker. A Pyrex glass beaker was used because of its strength at high
temperatures which were involved in this experiment. This beaker was
then placed on a tripod and gauze above a Bunsen burner and heated to
the experimenting temperature. When the desired heat was achieved a
1cm strip of magnesium ribbon was dropped into the beaker containing
the heated hydrochloric acid. The reaction from the magnesium ribbon
and heated hydrochloric acid produced a large amount of hydrogen
bubbles. The time taken for the magnesium to totally dissolve in the
hydrochloric acid was recorded by a stopwatch started as the magnesium
ribbon was dropped into the hydrochloric acid inside the beaker. A
thermometer, cleaned with distilled water and then dried before the
experiment, was used to stir the reacting materials and to ensure the
temperature of the hydrochloric acid remained constant. As the
thermometer was cleaned before the experiment it did not influence or
interfere with the results of the experiment.
We began this investigation by suiting up in lab aprons and goggles, we then gathered our materials, found a lab station and got to work. We decided to start with the magnesium in hydrochloric acid first, we measured out 198.5 L of HCl and put it in the foam-cup calorimeter and took initial temperature reading. We then selected a piece of magnesium ribbon and found its mass: 0.01g. This piece was placed in the calorimeter and the lid was shut immediately to prevent heat from escaping. We “swirled” the liquid mixture in the calorimeter to ensure a reaction, and waited for a temperature change. After a few moments, the final temperature was recorded and DT determined.

The Effect of Temperature on The Rate Of Reaction Between Magnesium And Hydrochloric Acid Planning I'm planning on investigating how temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed.

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.
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.
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.
from 10cm to 50cm to make it easier to see the difference in a graph.
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.
