Investigating Factors that Affect the Rate of Reaction Between a Metal and an Acid
Factors that may affect the experiment + fair test
The variables that could affect the rate of reaction are the
temperature, amount of magnesium, concentration of acid, surface area
of magnesium and volume of acid. The variable I am going to change is
the concentration of acid. I am going to measure how long it takes a
piece of magnesium(no more than 20m in length) to react in different
concentrations of acid. When magnesium is placed into hydrochloric
acid, it reacts by the acid particles colliding with the magnesium
particles. I am doing the experiment, using the magnesium in ribbon
form. This will give me a good set of results, if I was to use
magnesium powder, the reaction would be over fairly quickly, because
the surface area of magnesium will be a lot greater which will mean,
there will be a lot more collisions that take place between the
magnesium particles and acid particles, in a much smaller amount of
time. The collisions are likely to be more successful if the acid
concentration is stronger, this means there will be more acid
particles to collide with magnesium particles, to give you more chance
of a successful reaction. The variables I am going to keep the same
are the temperature, amount of magnesium, surface area of magnesium
and the volume of acid. By doing all this we will make sure that it is
going to be a fair test.
Preliminary work
We only used magnesium ribbon in sizes 20mm and 10mm, in 20ml of acid
and 10ml of water. Using the stopwatch to time the reaction we found
that: The 20mm piece of magnesium took 40.16 seconds to fully react in
the acid, and the 10mm piece of magnesium took 35.84 seconds to
dissolve in the acid. In out main experiment we are going to choose a
15mm piece of magnesium with acid. The experiment will be repeated
three times to make sure our results are accurate.
Investigation to find out if changes in concentration of acid affect the rate of a chemical reaction
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.
Investigating Factors Which Affect The Reaction Between Chalk and An Acid. Introduction: Chalk is just one of the many forms that calcium carbonate can take. It is made of the mineral remains of sea creatures from millions of years. ago.
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.

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.
· When I have collected my results I will place them in a table like
that the rate of reaction must be fast enough to make as much of the
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
Investigating the Effects of Temperature on the Rate of Reaction between Magnesium and Hydrochloric Acid
Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different concentrations of acid reacting with magnesium in two separate experiments, which will hopefully prove this initial prediction. [IMAGE][IMAGE] During my science lesson I have learnt the following information that has enabled me to plan my investigation.
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.
