Answer Cannot measure surface area of a powder. Kinetics is the study of rates of reactions. After, say every 20 seconds we read the volume of gas in the syringe. In this experiment I will have to make sure I am careful with all glassware in case it breaks and if it does to make sure it is immediately cleaned up. This is because a solution with a higher concentration will produce a lot of acidic fumes. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt.
Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. However, if this energy is not produced, a reaction will not take place, so not all collisions result in a reaction. There are many variables that affect the rate of this reaction such as the following: 1. Conical Flask - the gas syringe had to be able to be a perfect fit into the conical flask because the idea is to trap the contents of all the reactants to be able to get an accurate reading and find the amount of gas produced. The solution has to have a total volume of 50 ml. 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. Beaker - this holds the contents of the hydrochloric acid and water temporarily until the measuring cylinder is used because it ensures safety instead of pouring the hydrochloric acid from the glass bottle which was quite heavy and difficult to handle the beaker allowed me to clearly see the amount I was using.
Two chloride ions bond to one calcium ion. Concentration Pressure for gases 3. The concentration of hydrochloric acid… 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. The rate of reaction increases when the surface area of a solid reactant is increased. I am very happy with how everything turned out with this experiment and I am sure that the results that I have gathered are accurate. This also proves that activation energy does not play a part because if this did the gradients of the lines would not increase by the amounts they did. · I will heat the hydrochloric acid to 30 degrees.
Repeat three times for each concentration of acid · I will use the same method with the hydrochloric acid 0. At this point I am able to answer my main hypothesis which was how does changing the concentration of acid affect the rate of reaction between hydrochloric acid and calcium carbonate? Consider the weathering of beautiful marble statues from antiquity. Safety goggles for eye protection are recommended and lab coats are. Water turns a muddy color, and a white sediment can be observed. · 30g of calcium carbonate.
Catalysts: Catalysts are substances that change the rate of a chemical reaction without being changed in the reaction. Acid obtained in this method is called waste acid. My hypothesis was correct, as the concentration gets higher the reaction creates more Carbon Dioxide per. If I was to test this experiment again, the only thing that I would change would be to use higher concentrations of Hydrochloric Acid. Rate is a measure of a change that happens over a single unit time. Also in this report will be an outline. Diluted 1ml test tube 2 24 minutes and 18 seconds Diluted hydrochloric acid 1ml went white and was fizzing; the test tube had gathered around 6 cm of condensation.
Catalytic converters in car exhausts contain expensive platinum and rhodium sprayed thinly on to a honeycomb structure made of a ceramic material. It is a highly corrosive, strong mineral acid with many industrial uses. There will be an instantaneous reaction with the formation of bubbles — the release of carbon dioxide. · 30g of calcium carbonate. Therefore resulting in a quicker reaction.
However, if you cut 1x1x1 cm cubes of calcium carbonate, and perform experiment, then repeat with one cut in half etc. I think this will happen because when the acidity is higher the solution is stronger which then speeds up the reaction process. We could get the right amount of results of this, so we then tested the other extreme - the lowest molarity. Copy the above graph on your answer sheet and sketch the curve you would obtain if double the volume of hydrochloric acid solution of half the concentration as in the example above is used instead, with all other variables kept constant from the original. By neutralizing the acid, the calcium carbonate is able to stop or significantly decrease pain from conditions such as acid reflux and indigestion. An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances.
For both variables I recorded the time it took for 50cm3 of carbon dioxide gas to be produced. Also, I must be careful especially with the stronger molar acid because it will be corrosive so I must make sure I do not spill it on my hands or more especially in my eyes. Thus if the collisions double then the reaction between Magnesium ribbon and Hydrochloric acid will also more or less double. This substance is very caustic, so it requires careful handling: even if a small drop gets on the skin, it will cause a severe chemical burn. Temperature; when the temperature increases the particles moves faster, causing more collision in a certain time. I also predicted that on my second graph that shows the rate of reaction it would be a steady curve increasing with the temperature and as you can see it is.
