Investigate the effect of concentration on the rate of reaction between magnesium with hydrochloric acid.

Extracts from this document...


To investigate the effect of concentration the rate of reaction of magnesium with hydrochloric acid I am going to perform this experiment in order to discover how the concentration of an acid affects the rate of the reaction. I am going to perform this test using the following apparatus: A cylinder, Beakers, Stop Clock, Thermometer, goggles, and scissors. I am going to keep all my apparatus at the same room temperature and I am going to do this experiment 3 times in order to maintain a certain level of accuracy. After doing this experiment 3 times, I will average all of the results. The acid in which I am going to use in this experiment is 1M in strength. What I will do is I will use 50cm3 of acid for the first lot of magnesium. I will then take away 5cm3 of the acid and replace it with water so it makes a complete beaker full of 5cm3 water and 45cm3 of acid. I will then continue doing this until I have reached 25cm3 of acid and 25cm3 of water. ...read more.


1. Measure 50 cm3 of water into a 50cm3 measuring cylinder. 2. Transfer the Acid from the measuring cylinder to the beaker. 3. Then add the 2.5 cm of magnesium ribbon. 4. Stir once and start the clock as soon as the magnesium is dropped in the acid timing how long this takes to dissolve using the stop clock. 5. Repeat this using the measurements as stated in the results table. 6. Make sure that the experiment was repeated 3 times for more accuracy. 7. Average all the results up to get a final set. It is important that the beakers and all apparatus are being supervised at all times so that the most possible accuracy is maintained. If it is required, then ensure to repeat any odd looking results. Try and ensure that all measurements are as accurate as possible, to ensure fairness amongst all of the solution. Analysis I found out that the higher the concentration of the acid, the quicker the magnesium is able to react and dissolve into the solution.

I do believe that there was a couple of anomalous result, and I will highlight these on a second results table below. Exp No Volume of Acid Volume of Water Time in Seconds (1) Time in Seconds (2) Time in Seconds (3) Average 1 50 0 147 134 138 139 2 45 5 191 190 192 191 3 40 10 216 210 211 212 4 35 15 367 334 340 349 5 30 20 474 443 461 459 6 25 25 540 539 541 540 I do believe that I would have been able to make the experiment ever so slightly better by improving a couple of things. 1. I would have tried to keep the surrounding temperature at the same temperature if possible. 2. I would make sure that all of the magnesium ribbon is cut at exactly the same length. 3. I would have tried to make sure that we were using the same taps. 4. I would have possibly redone a few more of the results which I believe to be anomalous. 5. I think the experiment would be even more accurate if I had done the experiment more then 3 times. 6. I would use brand new magnesium ribbon, due to the fact that the old magnesium ribbon had formed an magnesium oxide layer. 1 ...read more.

    To investigate the effect of temperature on the rate of reaction

    4 star(s)

    Surface area of a solid reactant The surface area of the solid reactant can affect the rate of reaction. This is because the two types of molecule can only bump into each other on the surface of the solid. Therefore, simply, the larger the surface area of the solid, the faster the reaction will be.

  2. to investigate how the concentration affects the rate of the reaction

    Therefore using a more concentrated acid would increase the rate of the reaction . * Temperature: this is the degree of hotness of a substance. Increasing the temperature of a reaction by a small amount can double the rate of the reaction.

    The first thing that we shall do is to prepare our work area where we will be doing the experiment, clear anything that could cause an obstruction or any risk. The next thing to do is to simply gather together, and not set up, all equipment that we shall need.

  2. The Effect of Concentration on the Rate of Reaction.

    The graph shows that as the concentration of the hydrochloric acid increases, the rate of reaction also increases. The line should travel through the origin (0,0) because it is already known that when there is no hydrochloric acid in the solution, no reaction will take place between the water and the calcium carbonate chips.

    will record the width, length and weight of the Magnesium each time I conduct the experiment. To do this, I will need to use a micrometer, scales and a ruler. This is because if the width, weight or length varies with pieces of Magnesium, this means there are more particles,

  2. To investigate the effect of varying concentration on The reaction between magnesium ribbon And ...

    as there are more acid particles when the concentration is higher, then there will be more chance of them colliding with the Magnesium particles. However, if the concentration is lower, there are less particles, so the likelihood of them colliding with the Magnesium particles is smaller.

    I shall then drop a piece of magnesium ribbon into the conical flask, quickly stopper it with the tube connected to the gas syringe used for measuring gas in units of cubic centimetres, start the stop watch, and wait until 35 cc of hydrogen has been produced.

  2. How the effect of concentration affects the rate of a chemical reaction

    It is important to do this as soon as the Mg is added because if it is not, the results will be adversely affected and will not be as accurate as they could be. 6. When the Magnesium has just completely dissolved stop the stopwatch.
