Rate of reaction between magnesium and hydrochloric acid coursework Rating: 7,2/10 308 reviews

The rate of reaction between magnesium and hydrochloric acid is a common topic in chemistry coursework. This reaction is used to demonstrate the concept of a rate of reaction, which is the speed at which a chemical reaction takes place. It can be influenced by various factors, such as the concentration of the reactants, the surface area of the reactants, and the presence of a catalyst.

To study the rate of reaction between magnesium and hydrochloric acid, one can set up an experiment in which the reactants are placed in a container and their reaction is observed over a set period of time. The rate of reaction can be determined by measuring the amount of a product that is formed, or by measuring the pressure change in the container as the reaction takes place.

One of the factors that can influence the rate of reaction between magnesium and hydrochloric acid is the concentration of the reactants. If the concentration of the hydrochloric acid is increased, the rate of reaction will also increase. This is because there are more reactant particles present, which increases the chances of a successful collision between the reactants.

The surface area of the reactants can also affect the rate of reaction. If the reactants are in the form of a fine powder, the surface area is increased, which increases the rate of reaction. This is because there is more surface area available for the reactants to collide, which increases the chances of a successful reaction.

A catalyst can also affect the rate of reaction between magnesium and hydrochloric acid. A catalyst is a substance that speeds up the rate of a chemical reaction without being consumed in the process. In the case of the reaction between magnesium and hydrochloric acid, a catalyst such as zinc can be added to the reactants to increase the rate of the reaction.

In conclusion, the rate of reaction between magnesium and hydrochloric acid can be influenced by various factors, such as the concentration of the reactants, the surface area of the reactants, and the presence of a catalyst. Understanding these factors is important in the study of chemical reactions and can help to predict the outcome of a reaction.

rate of reaction between magnesium and hydrochloric acid coursework

Constant: -Amount of Hydrochloric acid 15 cm3 -Concentration of Acid 0. When the temperature rise, the energy on each of the acid particles increase, as they move faster, there is a bigger chance to hit the magnesium particles, this also increase the percentage of successful collisions, as a result, the reaction becomes much more faster, so it takes less time to take the reaction as the temperature rise. This is a theory that is used to predict the rate of a reaction. We are going to do an experiment on the rate of reaction. Hydrogen gas extremely flammable is generated in the experiment.

This reaction slows down and stops before all of the calcium has reacted. These are very hard to improve as human eyes cannot look at things very accurately, also I can just keep the temperature as low as possible to avoid the acid evaporate. Three reactions will be made for each test; this is done to gain the different averages. Collision Theory 3 Volume of hydrochloric acid,I will use excess amount of acid because this experiment is aimed to find out the time needed and volume of hydrogen given out by a certain amount of magnesium, so excess amount of acid is needed to dissolve all the magnesium. Magnesium chloride + HydrogenEquation of this reaction:Mg s +2HCl aq? I predict that when the concentration of the hydrochloric acid doubles, the rate of the reaction doubles. Therefore more reactant particles will have enough energy to react. Last reaction will have only 10 cm 3 of sodium thiosulphate.

Throughout the experiment, we diluted the This complies with my prediction. Background Knowledge There are four factors that can affect the rate of reaction and they all rely on the collision theory. Acid particles can collide only with magnesium atoms on the outside of the metal. Using larger concentrations of acid would give a bigger more accurate conclusion instead of just using 10 ml test tubes use 1 litre test tubes, this way graphs would be more spaced out and give an accurate form or curve. Secondly, the weight of the magnesium is not being the same every time, which may vary the volume of hydrogen given out. If our skin contact with the acid, we should immediately wash it under the tab water. Preliminary work:In this preliminary work, the aim is to find out the suitable length of magnesium ribbon, the suitable concentration of acid and the suitable volume of the acid, and the temperature range I plan to investigate.

How does the temperature of hydrochloric acid affect the rate of reaction between hydrochloric acid and magnesium

rate of reaction between magnesium and hydrochloric acid coursework

This means that, in this reaction, the magnesium is used up completely first, leaving extra hydrochloric acid behind. Candidate Name: Tejaswini Nareshkumar Candidate Number: 5160 Centre Number: 13317 - 1 - 3 star s This is a well written and researched piece of scientific writing. Heat energy is then released when the sodium thiosulfate crystallises. And when all the magnesium is used up, the line stopped. The equation for the reaction is: Mg s magnesium + 2 HCl aq hydrochloric acid MgCl 2 aq magnesium chloride + H 2 g hydrogen a Give two observations the student could make during the reaction. Continue timing until no more gas appears to be given off. This increases the rate of reaction without getting used up.

Does magnesium and hydrochloric acid produce heat? I also predict the hydrogen given out will be much faster when you increase the temperature. Magnesium is highly flammable, so we should keep it away from the fire. If it did rust our results would have been affected as another product would have been added to the reaction. Analysis: From my result table and my two graphs I have found that the more concentrated the acid, the quicker the reaction between hydrochloric acid and magnesium. Obtaining Results:The results collected from the experiments are shown on the table.

Rate of reaction The Effect of concentration on the reaction between magnesium and hydrochloric acid. The tube through the bung should be a short section of glass, and then a flexible rubber tube can be connected. I thought that this would happen because when there are more acid particles in the test tube the more chance there is of a successful collision. This reaction is an example of a single replacement. Page 2 of 82 i Where does the nitrogen used in the Haber process come from? They move more rapidly through the solution, they collide more often and more vigorously, so the chance of a reaction increases. If you increase the number of particles in the solution it is more likely that they will collide more often. Also I predict that this is going to be an exothermic reaction because of forming bonds between magnesium and chloride.

Secondly, It is obvious that when the temperature becomes higher, the reaction becomes much faster shown on the last two graphs , the gradient of 50 degree Celsius increase more rapidly than the 18 degree Celsius. Magnesium is highly flammable, so we should keep it away from the fire. Then the line stops as the magnesium finish. If the reaction is slow, the reaction rate is low. The ten respondents were randomly selected on the campus of University Wisconsin at Milwaukee.

We are using acid and magnesium strips to test the rate of reaction. How does magnesium react with hydrochloric acid? The products that will be formed are Magnesium Chloride MgCl2 and Hydrogen H2. Add 1m concentration of dilute hydrochloric acid to conical flask. I also predict that as the concentration doubles the rate of reaction will double, this is because there are more molecules in a given volume, in 2m hydrochloric acid there are twice as much molecules than in 1m of hydrochloric acid. The graph gives us a good device to prove that if you double the concentration the rate of reaction doubles.
