Involves and biting and a metal EssayThe Problem To investigate one of the factors affect the assess of chemical answer between a metal and an acetous. Background Knowledge The balanced equation for the response that takes channelise between atomic number 12 and hydrochloric acid is Mg + 2HCl == MgCl + Cl From this equation, we can already see that it involves and acid and a metal, therefore Acid + metal == salt + hydrogen The ionisation equation of the hydrochloric acid is HCl(aq) == H + Cl This experiment allow demonstrate the breaking of bonds. Bonds break in order to allow authorized atoms to re-arrange before the new bonds are formed.When magnesium reacts with the hydrochloric acid, a particle of this acid must clash with a particle of the magnesium with adequate power in order to break the bonds between the magnesium and the hydrochloric acid. This is cognise as the Collision Theory. The collisions between the particles must collide more(prenominal) often and with more sufficient energy in order for the rate of reaction to increase. Although, not e actually collision produces a successful reaction as they require a certain amount of energy to break bonds. This is called activation energy.The rate of a chemical reaction refers to the speed at which it happens, and different metals react at various rates. The progress of a reaction can be measured by the rate of a formation of a mathematical product or by the decrease of reactants. There are four main factors that can be alter to affect the rate of reaction between magnesium and acid 1. Surface area (of the reactants) 2. Concentration (of the reactant) 3. Temperature 4. The presence of a specific catalyst If the surface area were increased by using a magnesium powder, then the reaction would speed up, as there are more particles that are competent to collide with the hydrochloric acid.The products of a reaction are formed as a result of the collisions between the reactant particles. Co nsequently, if the concentration of a response is increased, collisions are more likely to occur. The more often the particles collide, the higher the chance that a reaction go away take place. Subsequently, the rate of a chemical reaction increases if the concentration of the reactant is also increased. This is also because the rate is proportional to the concentration. E. g. Diagram to illustrate a high concentration and a low concentrationWhen the temperature at which the reaction is carried out is increased, the energy of the particles also increases. As a result of this, the particles move much swift allowing them to collide more often with other particles. Therefore, as there are more collisions and these collisions are more energetic, the rate of reaction increases. Catalysts are used to speed up a reaction. These biological catalysts are extremely specific, therefore only speed up certain reactions. Every chemical reaction taking place has an exclusive enzyme catalyst (a n enzyme is a protein molecule produced in a living cell.)A catalyst will decrease the activation energy and forms an alternative path to help the collisions to be more successful. Safety As I will be using glass conical flasks and burettes, I will be very careful when handling them in case I harm myself or others by dropping them. The hydrochloric acid is also corrosive, which means that it is able to eat away at materials that it is within contact with. Again, I should manage this carefully and ensure that there are no vomitages. Water seems quite harmless, but if I spill any, it is possible that someone may skid or trip on it.For safety precautions, I will wear goggles and an overall and also tie my hair back. Method I will incur by attatching a plastic burette clamp to a clamp stand at a practical height to begin my experiment. I will then fill my water tub or so 1/2 full with water, and place it next to my clamp stand (so that the burette clamp is able to hole the burette above the tub. ) Next, I will fill my burette with tap water above 50cmi and attach it to my clamp stand using the burette clamp. Very quickly, I will swiftly disco biscuit the burette upside down and speedily submerge it under the water.Afterwards, I will produce the solution of hydrochloric acid and water using separate measuring cylinders. I will remove the bung that is tenia the conical flask, and pour in the measurements of hydrochloric acid and water. I will then drop the magnesium palm tree (which will be cut using scissors), replace the bung and swirl the solution for a second, whilst starting line the stop quantify. I will take readings every 10 seconds. Diagram Apparatus Burette speech tube Clamp stand Burette clamp Magnesium tape Distilled water Stop clock Conical flask Measuring cylinders (at least 2).
