I have used these concentrations to best simulate the lab results. Read off from the graph the time taken to produce this amount of gas. To change the concentration of a solution, we dilute it by adding water. Diagram showing activation energy: The faster the particles are going, the more energy they have. The methods were: Method 1: Collecting gas produced Reaction takes place in a flask. The reason why this happens is because at a higher temperature ions have more kinetic energy so they move through the solution faster so the ions will collide more often and more vigorously so there is a greater chance of a reaction happening as reactions happen when ions collide.
This increased speed increases the chances of the collisions between the reacting molecules. · I will use the same method with the hydrochloric acid being room temperature 22 degrees , 40, 50 and 60 degrees. The magnesium displaces… 1059 Words 5 Pages investigate the effect of temperature on the reaction rate of hydrochloric acid and magnesium. Answer The simulation assumes that everything is completely mixed at the start of the experiment. To find out how the temperature of acid effects the rate of the reaction between Hydrochloric Acid and Calcium Carbonate. When a reaction takes place, the particles of the reacting substance must collide with each other. The magnesium displaces the hydrogen in the acid, so it forms magnesium chloride and hydrogen gas.
Every 60 seconds for 10minutes we took readings down. In this simulation you will discover the effect on the rate of reaction of altering the surface area of a solid reactant, and explain this effect in terms of kinetic particle theory. This experiment looks at how the speed of a chemical reaction changes as you change the concentration of one of the chemicals involved. In my case the reactants are hydrochloric acid and magnesium ribbon… 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. Effect of temperature on the rate of reaction between magnesium and hydrochloric acid Apparatus: Magnesium strips 5cm Hydrochloric acid Water bath Clamp x 3 Clamp stand x3 Ruler Measuring cylinder 100ml Measuring beaker 50ml x2 Rubber tube Rubber bung Gas syringe Wire wool Stop clock Aim: My aim is to find out if heating the hydrochloric acid affects the rate of magnesium and hydrochloric acid. A chemical reaction is defined as the process that involves rearrangement of the ionic structure of a substance. The activation energy is the most important factor in terms of temperature and reaction speed.
Transfer this result to the. In a real experiment you will have to repeat the experiment and take the average. To observe the effect of a catalyst Manganese Oxide on the rate of decomposition of Hydrogen Peroxide. In the preliminary experiment I will investigate the suitable conditions for this experiment — the volume of hydrochloric acid to use and the surface area of marble chips. The heat energy is given to the surroundings; the temperature might go up making it feel hot.
· 30g of calcium carbonate. Oxidation this happens with most substances usually forming an oxide e. The more often they collide the more chance they have of producing a productive reaction. There are many variables that I can change, which are the temperature and concentration of the hydrochloric acid, and the mass and the The amount of hydrogen I will end up with when the reaction has completely finished will be the same for all the concentrations, but if a reaction is too slow and exceeds the set time I will stop taking results and it might not finish reacting. The first factor is: Temperature of reactants: When the temperature… 772 Words 4 Pages Effect of temperature on the rate of reaction between magnesium and hydrochloric acid Apparatus: Magnesium strips 5cm Hydrochloric acid Water bath Clamp x 3 Clamp stand x3 Ruler Measuring cylinder 100ml Measuring beaker 50ml x2 Rubber tube Rubber bung Gas syringe Wire wool Stop clock Aim: My aim is to find out if heating the hydrochloric acid affects the rate of magnesium and hydrochloric acid.
Carbonic acid is unstable, decomposing to give carbon dioxide gas and water. Surface Area; the smaller the pieces the larger the surface area becomes. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. Additionally catalysts was not the variable I chose, because this would only give me two results — whether the rate of reaction is faster with the catalyst or whether it is faster without the catalyst. 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 detailed investigation.
Scientific knowledge: Marble chips erode when they are exposed to acid rain or pollution. Furthermore the chips were dropped in the conical flask and the bung was immediately placed on the flask while the stopwatch was started. After examining the graph I found out that a distinct pattern exists connecting each experiment together. Measure the amount of hydrochloric acid used up per minute 3. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. The input variables are the ones that I can change in order to affect the experiment and the outcome variables are the ones I will measure to see how the input variable has affected it.
The increase in the concentration should be directly proportional to the increase of the reaction rate at a given time. My new list of apparatus looks like this: · Thermometer. · I will use 1g of calcium carbonate. I would set up the apparatus differently however. Apparatus: · Conical Flask · Measuring cylinders 15ml, 25 ml, 50ml, 100ml · 45 ml of hydrochloric acid 0.
Erosion is evident when you look at older marble buildings as in certain cases the erosion take a long time. The particles of any gas or liquid can only react if they are supplied with energy. I chose to measure the volume of carbon dioxide gas given off and by measuring the amount of carbon dioxide gas produced every 10 seconds for the main experiment because it was the two methods that are likely to give me the most accurate results. I tried this and the results were much more reliable to use and analyze. We had the option of the surface area, the concentration or the temperature as our independent variable to affect the rate of reaction. Visible changes can occur in the reaction mixture. It can also highlight some of the problems they are going to find with the real experiment, e.
