This means that will give out heat during the reaction. Fair Test To keep a fair test I will have to look into all the variables surrounding the experiment and only change the variable that I am testing on.
Surface area of Magnesium ribbon: If we study the energy level graph below you can see that more energy is given out than is used up. For stance, magnesium metal reacts with hydrochloric to form magnesium chloride salt while displacing hydrogen from the acid as hydrogen gas.
Also, the alloyed metal is used to make a large variety of other products, such as, artificial limbs, Acid and magnesium essay cleaners, optical instruments, recreational skis, wheelbarrows, lawn mowers, and outdoor furniture. The most vital need for it is on the cellular level.
Out of these 7 variables I have decided to investigate the temperature. Aims and objectives of the experiment The aim of this experiment is to verify the effects of surface area of solid reactants and concentration of aqueous reactants on the rates of acid-base chemical reactions.
In the body, magnesium is essential for many activities in the body including calcium utilization, cardiac function, energy production, many enzyme reactions, relaxation of muscles and restful sleep. The only difference is that at a higher temperature this maximum amount of hydrogen that can be formed, from the amount of hydrochloric acid and magnesium added, will be obtained quicker.
Magnesium assists with the production of cellar energy, regulation of calcium, manufacturing of protein and normal muscle contractions.
This diagram shows five solutions hydrochloric acid and magnesium ribbon that are reacting. My 3rd prediction, which is mentioned in the corresponding hypothesis, is that the temperature of the solution will increase, as it is an exothermic reaction.
Concentration of the acid If you increase the concentration of the acid you increase the number of hydrochloric acid particles in the solution. This heat energy will then be converted into kinetic energy and the atoms will collide more often. All the experiments have to be repeated at least two times to make an accurate set of results.
Also, in affect you are increasing the surface area of all the hydrochloric acid particles, and therefore there are more collisions. There were certain control variables which we had to make sure did not affect our results. Temperature affects the rate of reaction as explained in Collision theory.
The Controlled Variables constants: That is the main difference I would have made to our method, as the majority of the method was acceptable. If it sharply returns to its original position when I let go, it is air tight The test had to be repeated to straighten out any anomalies and keep the results as accurate as I could.
As the temperature increases the speed and the power at which the acid particles hit each other increases, making the number of successful collisions with the magnesium strip increase.
The original diagram shows how the solution will be with 1M hydrochloric acid and 5cm of magnesium strip. Clearly, the time taken for the magnesium to disappear when it is placed in different concentrations of 2HCL, is related.
Most product have been banned by the U. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. Apparatus- The apparatus used will stay the same because differences in size and shape may affect the outcome of the results although the beaker with the acid and reactant will be washed out and cleaned each time we restart the experiment in case traces of solution are left in affecting the outcome of the next experiment.
TimeThe longer the magnesium is left in the Hydrochloric acid the longer it has for the reaction to finish, so therefore there will be a greater yield of hydrogen. They do not need to have a specific storage procedure like that of the corresponding elements. Today, though it is chiefly produced by electrolysis of fused magnesium chloride.
More essays like this: Surface area of the magnesium Increasing the surface area is related to the concentration as you are exposing more magnesium atoms to hydrochloric acid particles therefore increasing the chance of collision. Equipment and Materials The following chemicals and reagents were required in the experimentation: Temperature influences the rates of reaction through kinetic energy, such that high temperatures increase the kinetic energy of reacting molecules therefore causing frequent collisions, which form products faster.
Magnesium Acid 10 20 30 40 50 60 10 20 30 40 50 60 5cm 30ml 4 15 34 45 55 - - - - - - - 2cm 30ml 5 10 14 17 22 26 32 37 40 45 47 49 2cm 20ml 1 5 6 9 12 14 16 18 20 22 23 25 From my preliminary results, I can see that the higher the acid concentration and the longer the magnesium, the faster the reaction time will be.
If they are moving faster the rate of reaction increases because the atoms will collide more often and more and the reaction will speed up.
These include the presence or absence of catalyst, temperature, concentration, and surface area of reactants. As the temperature increases the speed and the power at which the acid particles hit each other increases, making the number of successful collisions with the magnesium strip increase.
This is because no matter which temperature the solution is at the same amount of hydrochloric acid and magnesium is being used.
This means that the particles travel faster and collide with each other with a greater force. There are also many factors that I could record like the weight of the solution and the time it took for the magnesium strip to dissolve, but I am only recording the hydrogen produced.magnesium (Mg) is known as a chemical element with the atomic number of Hydrochloric acid (HCL) is a strong, colorless mineral acid used with many purposes.
Magnesium (Mg) is known as a chemical element with the atomic number of The silvery white solid is an abundant element found in the.

The rate for sulphuric acid ought to be higher than hydrochloric acid, because the more the acid proton, the quicker the acid proton dissociate.
However, when we consider about the spectator ions, SO42+ and Cl- there is a significant difference in size, Cl-. A major factor in the decay of the statue is acid rain, which prevents the formation of the oxide coat that would normally form on magnesium preventing corrosion in air.
