From beautiful Pine Beach New Jersey: Welcome to the world's most popular metal finishing website topic 11194 Magnesium ribbon and hydrochloric acid reaction 2001 Q. The magnesium displaces… 2895 Words 12 Pages I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. Roberts, Saher Shah, Leslie Garcia, and Taiss Hernandez Observing Chemical And Physical Properties This is a picture of the reaction of Magnesium and Hydrochloric Acid. I have a pure hunk of magnesium metal submerged in water. The duration of reactions were recorded as shown in tables 2 and 3 below.
I felt that when performing the experiment, I could have gotten some error from my temperature readings. When the mixture was filtered it was clear and resulted in a physical change. Clark 2002 explains that, finely divided chemical solids have greater surface area than chemical solids in lumps. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium. Does any one no Under What Conditions Does âMagnesiumâ React With âHydrochloric acidâYou should have started another thread.
Optional If the flame of a butane fireplace lighter is held above the bursting bubbles, they will produce audible pops as the hydrogen ignites. An average percent error of 0. The magnesium hydroxide reacts with malic acid to form magnesium malate which will be precipitated at the bottom. This demonstration may also be performed using a document projector if a dark background is used. 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.
As mentioned, hydrochloric acid is a strongly ionizing non-oxidizing acid, and magnesium is a very active metal. You'll get to know more about this later, in Chemical Energetics. Chemical reactions between substances are caused by the collision of particles. You will observe the magnesium metal being consumed. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. Hydrochloric acid is a corrosive liquid. Hi, yeh the magnesium ribbon reacts with the hydrochloric acid in a redox reaction, where the magnesium is reduced and hydrogen is oxidised as it gains electrons from the magnesium.
Allow about 5 minutes for this demo. Retrieved March 8, 2012, from chemguide. Commonly known as Epsom salts, magnesium sulfate treats pre-eclampsa and eclampsia. Suspected errors Error Significance Possible Improvements For the 10 cm magnesium metal used, there was slight variation in weight. The copper wire with the magnesium was then lowered into the buret and held in place with a one-holed rubber stopper to make sure the wire would stay in place and would not fall to the bottom.
The rate of gas bubbles The independent variables Increasing concentration of hydrochloric acid: This will be changed by changing dilution factor. Each experiment run will need 50 cm 3. 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. Magnesium is an alkali earth metal, found in group two S - Block of the periodic table, it forms 2+ ions, and is quite reactive, upon heating it will burn with a brilliant white glow. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. Background Knowledge There are four factors that can affect the rate of reaction and they all rely on the collision theory.
This resource image was supplied by science photo library © Andrew Lambert Photography. Clean if necessary by rubbing lengths of the ribbon with fine sandpaper to remove the layer of oxidation. The experiment itself takes only a few minutes. The most rapid gas bubbles were observed in the acid reactions with powdered Magnesium metal. For the Magnesium ribbon, the lengths of the Magnesium ribbon used will be constant, while quantities of powdered Magnesium metal in grams will be equivalent to the weight of the length of magnesium ribbon used. Magnesium ribbon is a flammable solid.
Half fill the trough or bowl with water. Powdered solids produces rapid reactions than the same solids in single lumps. The more and harder they collide, the faster the reaction time will be. The heat sort of increase the rate of reaction at a certain time. Acid is acid; if you put water in acid, no biggy, just liquid, but if you put acid in water. The mixture of sodium hydrogen carbonate and water created a cloudy liquid. Please forgive any resultant repetition or failures of chronological order.
