The magnesium displaces… 2895 Words 12 Pages I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. These types of reactions will always produce a salt and hydrogen gas. 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 Determination of end of reaction was sometimes uncertain. Chemicals… 2009 Words 9 Pages concentration on the reaction between magnesium ribbon and hydrochloric acid Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. The reaction happens at the interface. One fourth of the third cup is removed at the lip.

mg hcl reaction

The other product or magnesium chloride is a compound that has an atomic weight of 95. Be sure to include units. Ways that I could record my experiment There are several way which I could record my experiment. The more and harder they collide, the faster the reaction time will be. Dissolve the magnesium as a demonstration. From the length of the small piece, its mass is calculated. This type of chemical reaction often involves either hydrochloric or sulfuric acid, which are strong acids.

How to Balance Mg + HCl → MgCl2 + H2 (Magnesium + Hydrochloric Acid)

mg hcl reaction

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. Then propose two different factors which will alter this rate. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant in order to carry out a deta. The tube through the bung should be a short section of glass, and then a flexible rubber tube can be connected. Therefore, this study intends to investigate the effect of concentration and surface area of reactants on the rate of chemical reactions. Hydrochloric acid is a strong electrolyte; it will split up completely into H+ and Cl- ions in solution.

The Reactivity of Magnesium Metal with Hydrochloric Acid

mg hcl reaction

At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. To find the molar mass of magnesium, I took the mass of the magnesium used divided by the number of moles used. Therefore, determine the mass of your uncut length of magnesium ribbon. Include the heat of reaction calculated above. Introduction In acid-base chemical reactions, there are four main variables, which influence the rate of reaction. The process was repeated for one more trial. To balance this equation, you have to know the charges of the ions.

Lastly, since the ideal gas law is not precise, error could have come from that. Retrieved March 8, 2012, from newton. For this kind of reaction to occur, an element that is more reactive has to displace one with less reactivity. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph. The reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3.

So the question becomes, is the reduction potential of the Mg positive or negative. The products that are formed during this reaction are hydrogen gas and magnesium chloride. So, the… 2357 Words 10 Pages rate of reaction between magnesium ribbon and hydrochloric acid Rates of Reaction: Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid. The duration of reactions were recorded as shown in tables 2 and 3 below. Other equipment may be requested if you provide a list the previous day. The formula equation for this experiment The factors that may affect the rate of reaction are as follows: · Temperature of the Hydrochloric Acid · Mass of the magnesium ribbon used · Concentration of the Hydrochloric acid · Surface area of the magnesium ribbon used All of these factors will change the rate of reaction because of the Collision Theory.

Balance Chemical Equation

mg hcl reaction

Never look directly at burning magnesium. An average percent error of 0. Single replacement reaction also are not reversible reactions. This is a low significance error since we based mostly on the disappearance of magnesium into the acid rather than disappearance gas bubbles. The magnesium reacts with the acid, producing visible bubbles of hydrogen gas. These include the presence or absence of catalyst, temperature, concentration, and surface area of reactants. Find the percent error for the experiment.

Balance Chemical Equation

mg hcl reaction

Matter interacts to form new substances through a process called a chemical reaction. Design an experiment using the reaction between magnesium and hydrochloric acid to verify this statement quantitatively. The most rapid gas bubbles were observed in the acid reactions with powdered Magnesium metal. In my case the reactants are hydrochloric acid and magnesium ribbon. Next, the magnesium strip was wrapped around the tip of a copper wire, and was then encaged by the same copper wire by wrapping the wire around the magnesium. As the magnesium is used up, the rate falls. Using forceps, place the magnesium ribbon into the Petri dish.

Even after disappearance of magnesium ribbon, gas bubbles were evident, implying the reaction was incomplete. Data Trial 1 Trial 2 Mass of Mg sample, g 0. Make sure you put on your personal protective clothing and safety goggles. Magnesium ribbon is a flammable solid. Because magnesium has such a low density, it is not practical to weigh small pieces. The possible ways are as follows: Amount of gas evolved I could use a gas syringe to collect the gas that will evolve from my experiment. The dilute acid is corrosive.

Circumference of Mg ball cm 2. A reaction rate is how fast or slow a reaction takes place. 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. Assume the copper cup would not react with the materials used in the experiment. Students may be given the option of selecting only one of the behaviors listed, in keeping with cooperative learning procedures, if you so choose. Because of this effect the reaction won't truly go to completion during the class period and the indicator doesn't change as much as in the first flask. Wash your hands before leaving the laboratory.
