The strip could have also been of different thickness, which again would have altered the results slightly. Distilled water was squirted into the one-holed rubber stopped to make sure the buret was completely filled. Prediction: The 'Collision Theory' says that particles can only react if they collide with enough energy for the reaction to take place. We carried out an experiment as a class to investigate how concentration effected the rate of reaction. An average percent error of 0. This beaker was then placed on a tripod and gauze above a Bunsen burner and heated to the experimenting temperature.

Overall my experiments went well and I feel I achieved the results I set out to obtain. The results were supervised by another person to ensure the results were taken accurately. The information recorded was then interpreted into a graph and compared to the hypothesis. If the strip was quite old it may not have been as reactive as it would have been previously when newly cut. The particles collided with more energy in the higher concentrations of acid, compared to the mostly water solutions in which particles had little or no energy to move or collide. If not, you must ask the teacher to clarify for you exactly what the question is.

This was then poured into a clean Pyrex glass beaker. When hydrochloric acid is added with magnesium the result is a salt called magnesium chloride. The possible improvements that could be made to this experiment are that the concentrations of acid were measured and checked to ensure that they were all the same; the acid could be heated in a water bath to increase accuracy in heating the hydrochloric acid and the magnesium ribbon should be measured and weighed to ensure that the thickness of the ribbon didn't affect the amount of material being used. Cuts when polishing the magnesium metal are possible. To make sure the equipment is all air tight I had to attach the equipment together and pull the syringe up. The experiment will be carried out at room temperature 25 0C The study variables are summarized in the table below: Variables Operationalization of variables The dependent variables The duration of reaction, time taken for Magnesium to dissolve in hydrochloric acid completely measured using a stopwatch in seconds. You see I'm trying to investigate the reaction kinetics of magnesium and different acids and concentrations, this could have a huge effect on the reaction kinetics, so it's vital that I'm sure of where the ions are coming from to make a prediction! As I watered down the solution it took increasingly longer for the reaction to take place.

The effect of temperature on the rate of reaction between magnesium ribbon and hydrochloric acid

magnesium ribbon and hydrochloric acid experiment temperature

This is because there are more particles of acid to collide with the metal - The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium Aim To investigate if the temperature of hydrochloric acid will affect the rate of reaction between hydrochloric acid and magnesium. The reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3. There was one obvious anomaly; this could be because of a number of reasons, human error through poor result recording or not stirring the magnesium ribbon well enough, difference in magnesium ribbon size or a surge of gas to the Bunsen burner resulting in a sudden decrease of heat. The aqueous vapor pressure was found using a chart. The first factor is: Temperature of reactants: When the temperature increases the particles… 2086 Words 9 Pages Title: The Effect Temperature of Sodium Thiosulfate Has On The Rate of Reaction with Hydrochloric Acid Statement of Inquiry: What is the effect of changing a factor on the rate of chemical reaction? Precautions Keep magnesium away from ignition sources such as open flames.

The experiment itself takes only a few minutes. Each experiment will also be repeated 3 times to find an average. The Collision Theory is based on the idea that for a chemical reaction to take place, it is necessary for the reacting particles to collide with each other with enough energy to break or form new bonds between the other particles, which is called a successful collision. Getting an answer to a question isn't nearly as important to your education as fully understanding the question. Reactants with high surface area provide a greater binding surface for other reacting molecules, and therefore increase the number of successful collisions at any moment.

Rate of Reaction of Magnesium and Hydrochloric Acid

magnesium ribbon and hydrochloric acid experiment temperature

Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. I also needed safety goggles at all times to protect my eyes from the corrosive hydrochloric acid. However the acid is in excess, so it is mainly the loss of magnesium surface area becomes smaller that causes the change in the rate. Therefore, this study intends to investigate the effect of concentration and surface area of reactants on the rate of chemical reactions. The obtained results have been plotted as a line graph of the temperature of Hydrochloric acid against reaction time. Ensure that there are no naked flames.

It is clear that anomalies will occur in experiments like these because there is room for inaccuracy. This brought a slight confusion in stopwatch reading. Other factors, although I tried to prevent this, could have maybe affected my experiments. Planning In this experiment I am going to find out how concentration of acid affects the rate of reaction with magnesium ribbon. Table of Results Above is a table showing us the results that I have obtained after conducting the experiment. Given that, the experiment was carried out under the same conditions, the data obtained are reliable and generalizable.

In gases and liquids, particles are in constant motion. Find the percent error for the experiment. If there is magnesium left over, you ran out of acid before you dissolved all the magnesium, so you had excess magnesium. The hydrochloric acid should be about 1M for a reasonable rate of reaction. A chemical reaction is defined as the process that involves rearrangement of the ionic structure of a substance. Chemical reactions between substances are caused by the collision of particles. These strengths would determine the rates of reactions.
