The final reaction has the same amount of particles of acid and the magnesium, but the magnesium has been cut to increase the surface area. I could also change the acid reactant to sulphuric acid or phosphoric acid to see and compare the results with different molecular make-ups.
This shows that the Reaction between hydrochloric acid and magnesium essay of reaction gradually increases with the surge becoming more pronounced with a greater concentration of Hydrochloric Acid. I tried this but the reaction happened very quickly and the results of the volume of hydrogen were very spread out.
Some reactions are very fast, e. This makes the acid particles more likely to have more successful collisions each second than the original reaction. This initial energy is known as activation energy AE and is needed to break the initial bonds.
For example, a 2M acid will have twice as many particles per 20cm3 as a 1M acid. And the equipment was laid out like this: Using the less reactive metals like zinc, aluminium, iron or lead enables me to test the higher concentrations like 3M or 4M because the reaction will go slower so I will be able to read the results off the syringe properly.
Reaction rate between magnesium ribbon and hydrochloric acid Essay Sample Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen.
We half filled the plastic tub with water We filled the measuring cylinder full of water and put our thumbs over the top so that no air bubbles could get in. Table 1 A table of study variables and operationalization of the study variables Prediction Given that, powdered Magnesium metal has a high surface area than equivalent lengths of Magnesium ribbon, we predict that the former will have shorter duration of reaction with hydrochloric acid than the latter.
Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. When I set up the experiment I had to make sure the apparatus is tightly attached at the vulnerable points where some of the hydrogen could escape, like where the rubber tubing connects to the syringe.
It is based on the idea that for a chemical reaction to take place, the reacting particles have to hit each other hard enough to break or form new bonds. The experiment will be carried out at room temperature 25 0C The study variables are summarized in the table below: Background to investigation Before we started the main experiment there were a few things we had to sort out: This would mean that the carbon dioxide would have gone straight into the gas syringe instead of having to travel all the way up the measuring cylinder.
Most of the equipment is glass so I had to be careful not to damage it, as shards of glass can cut though skin. 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.
The rate of a chemical reaction is a measure of how fast the reaction takes place. This part of the apparatus has to be air tight to prevent any gas escaping from the apparatus. The main control variable which we could not control was the room temperature.
The experiment will be carried at a room temperature 25 0C. I have supported this with the explanation of the collision theory above. There were certain control variables which we had to make sure did not affect our results.
Some results around the middle were found to be slightly affected with slight anomalies little bumps in the line, but these were minor and the line was mainly smooth. Overall, I believe that I have enough evidence to support my conclusion, however different equipment and more data would give me a more confident and precise conclusion.
We took all of our measurements in the summer, and every day we measured the room temperature to make sure that there was no major difference between days.
The other variables are the temperature of the acid at the beginning, the volume of acid, the surface area of the magnesium strip, the length of the magnesium strip and if the magnesium strip is cleaned or not.
To get the initial rate I had to plot the first two results sec of every concentration and work out the gradient from this. This will be changed by changing dilution factor.
The quantity of the Magnesium for each test will be held constant. In this investigation we will test different concentrations of acid reacting with magnesium to see what effect it has on the rate of reaction, this will be a moderate speed reaction.
I wrote down the gas level on the syringe every 5 seconds over a maximum of seconds 2 minutes. This is as shown in the equation below: The Controlled Variables constants:- Reaction Between Hydrochloric Acid and Magnesium Introduction In the reaction between hydrochloric acid and magnesium, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas.
All chemical reactions involve reactants which when mixed may cause a. the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen.
