Therefore, this study intends to investigate the effect of concentration and surface area of reactants on the rate of chemical reactions. A constant amount of excess HCl is reacted with varying amounts of magnesium solid. 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. During a lab experiment with magnesium and hydrochloric acid, Curious Carl observed bubbles being produced. I hope this was helpful.

New York: Oxford University Press. <>
The reaction from the magnesium ribbon and heated hydrochloric acid produced a large amount of hydrogen bubbles. The rate of reaction of magnesium with hydrochloric acid Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. For stance, magnesium metal reacts with hydrochloric to form magnesium chloride salt while displacing hydrogen from the acid as hydrogen gas. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. 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. The volume of the hydrogen gas produced will be measured at room temperature and pressure. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. develop a relationship between the mass of magnesium reacted and the volume of … Figure 1: Experimental set-up of HCl-Magnesium reaction.

Cumulative average of reaction duration of: I tried this but the reaction happened very quickly and the results of the volume of hydrogen were very spread out. In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. It is quite reactive giving vigorous reactions towards acids. Therefore, considering concentration factor and surface are factor of reactants it is evident that the rate reaction curve trends would not be linear as expected, but rather exponential. I am reacting different masses of Magnesium with hydrochloric acid to find the temperature change. <>
Repeat step 5 and 6 for 2M, 1.5M, 1M, and 0.5M HCL and keep all the acids ready on the working bench. The data you obtain will enable you to answer the question: Since magnesium has only one valence and it reacts easily with HCl, it’s easy to generalize to other metals and acids. Hydrochloric acid (HCL) is a strong, colorless mineral acid used with many purposes. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen.

Pick one piece of Magnesium ribbon drop in the first prepared acid in the conical flask and immediately start your stopwatch. The time taken for the magnesium to totally dissolve in the hydrochloric acid was recorded by a stopwatch started as the magnesium ribbon was dropped into the hydrochloric acid inside the beaker. Reset your stopwatch, a repeat steps 9, 10 and 11 for the subsequent acids. Clark (2002) explains that, finely divided chemical solids have greater surface area than chemical solids in lumps. The experiment will be carried at a room temperature 25 0C. the heated hydrochloric acid. I was suggested to use 20cm3 of hydrochloric acid and 5cm of cleaned magnesium ribbon, and take the volume of hydrogen in the syringe every 10 seconds for the preliminary experiment to. Therefore, the errors were unidirectional therefore consistent. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas. Materials: Mg ribbon 3 Petri dishes 1.0 M HCl 1.0 M boric acid 1.0 M acetic acid Procedure: 1. In further investigation to keep this variable controlled would be to have the temperature of the HCl tested with a thermometer before the acid is combined with the magnesium. I am reacting different masses of Magnesium with hydrochloric acid to find the temperature change. Similarly, Gallagher & Ingram (2001) say that the depletion of H+ during the reaction of magnesium and HCl is factor that slows down the reaction as time goes on. Expt Sulphuric 3 3 should add measured amount of magnesium … Label the Petri dishes with each acid. In the zinc and hydrochloric acid experiment the learners collect gas in a balloon. %����

This is because the hydrogen ions (H+) from the acid I have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. Place a Styrofoam cup into a 250 mL beaker as shown in Figure 1. In this experiment the reaction between hydrochloric acid solution and magnesium ribbon is used to investigate the effect of reactant concentration on the rate of reaction. There will be an explosion. Barrans, R. E. (2012, March). X Research source The chemical equation for this experiment is: Mg (s) + 2 HCl (aq) --> MgCl 2 (aq) + H 2 (g). Reset your stopwatch timer and prepare a gas delivery system including water bath as shown figure one below. 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. the heated hydrochloric acid. Wrap the magnesium pieces immediately in an aluminum foil to prevent them from being re-oxidized. Measure out 30 mL of citric acid solution into the Styrofoam cup. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. Then ready with the stopwatch we tipped the magnesium in to beaker and put in the cork with the rubber tubing and started the stopwatch.

The experimentation procedures followed were standard for all the two sets of experiments conducted, including data collection mode. Even after disappearance of magnesium ribbon, gas bubbles were evident, implying the reaction was incomplete. THE EFFECT OF SURFACE AREA ON REACTION RATES. In addition, impurities may form on the surface of the magnesium metal therefore, slowing further the rate of reaction. The following chemicals and reagents were required in the experimentation: Apparatus and personal protection equipment. Before starting the investigation, I decided to do some research about magnesium and hydrochloric acid. Place about 5cm depth of the acid in each of the five test tubes; Place a small piece of each of the three metals above. Factors That Affect Reaction Rates - Chemwiki 2015. (2002). The magnesium looked like a gray powder. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph This is intended as a class practical. 2. The chemical reaction between hydrochloric acid and magnesium produces magnesium chloride and hydrogen gas.

Make sure you put on your personal protective clothing and safety goggles. The Reaction of Magnesium with Hydrochloric Acid. The study variables are summarized in the table below: Table 1 A table of study variables and operationalization of the study variables. The ratio of the cumulative reaction duration above gives 104.8 sec/58.8 sec = 1.78. To determine the hypothesis, you would first find the time of reaction actually effected by the concentration of HCL solution. To measure the effect of concentration on the average rate of a reaction. He identified the gas as being hydrogen. The Reaction of Magnesium with Hydrochloric Acid. Part I Citric Acid plus Baking Soda 2. This experiment determines the stoichiometry of a reaction of magnesium and HCl by measuring the pressure of the hydrogen gas produced using a PASCO Absolute Pressure Sensor and a PASCO Science Workshop 500 computer interface. This is as shown in the equation below: 2HCl (aq) + Mg (s) => MgCl2 (aq) + H2 (g). However, Barrans (2012) highlights that the reaction rate between magnesium metal and HCl follows first order kinetics. We also predict that reaction of powdered Magnesium metal with highest concentration of hydrochloric acid will take the shortest duration of reaction. The experiment will be carried at a room temperature 25 0C. Monitor the reaction progress closely and stop your running stopwatch when the Magnesium ribbon completely dissolves in the acid and record the reaction duration in seconds in a data sheet. Chosen experiment: The task is to alter and record the different temperatures when magnesium ribbon is places hydrochloric acid. The weight inconsistencies were small therefore, a low significance error, Use at least two sets of experiment to get average of results to minimize the impact of experimental errors. Hypothesis: Powdered Magnesium metal will reduce the reaction duration by a half if used in place of equivalent length of magnesium ribbon, when reacted with hydrochloric acid. 3 0 obj
