After doing so clamp the tube in to place making sure that its horizontal. Truthfully, an electric car produces almost no pollution, but it can go. Pour the acid in the conical flask and quickly seal it with the bung attached to the delivery tube. 路 I will heat the hydrochloric acid to 30 degrees. 路 I will use the same method with the hydrochloric acid being room temperature 22 degrees , 40, 50 and 60 degrees. We are going to time how long it takes to make 150 cm 3 of gas.

Rate of reaction between Hydrochloric Acid and Calcium...

rate of reaction between calcium carbonate and hydrochloric acid results

The aim of this investigation is to find out how the concentration of hydrochloric acid affects the rate of reaction with calcium carbonate. We also wore goggles whilst the experiment was taking place in case any of the solution may have managed to shoot into our eyes. To improve the reliability of my evidence I could have taken readings more often for example every ten seconds for a longer amount of time such as five minutes. Acid rain is one of the top degradation agents for marble artefacts around the world. 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. The one major problem with my experiment was that I did not continue to measure the amount of gas produced for enough time so I could not see that all the lines in my graph would level of and meet at the same place I could solve this easily by repeating the experiment and taking reading every twenty seconds for longer than I did for about five minutes instead of the previous two. There were certain control variables which we had to make sure did not affect our results.

What Happens When Calcium Carbonate and Hydrochloric Acid Meet in the Stomach?

rate of reaction between calcium carbonate and hydrochloric acid results

Reaction between zinc and dilute hydrochloric acid What we observe over time is that gradually the zinc disappears and bubbles of gas appear. Aim To investigate the size of the chips and the volume of hydrochloric acid used, so that in the main experiment I have little difficulty and reasonable values. As the carbon dioxide escapes to the air, of the flask and its contents will decrease. In my experiment I will change the temperature of the hydrochloric acid. Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In this investigation the substance that is formed is Calcium Chloride, Water and Carbon Dioxide. I will record my results in a table like the table below: Time seconds Volume of gas attempt 1 cm3 Volume of gas attempt 2 cm3 Average volume of gas cm3 0 20 40 60 80 100 120 Preliminary work: As preliminary work I will perform a dummy run, which is a practice run of the real experiment.

The most they differed by was 1. This means that the calcium carbonate does not affect the rate of reaction, only the concentration of the hydrochloric acid does. Experiments 2 and 3 can be used to work out the order of X. I predict that the reaction will occur as shown below: Calcium + hydrochloric calcium + water + carbon Carbonate acid chloride dioxide. This can cause heavy erosion in limestone, which is largely composed of calcium carbonate.

Reaction rate of Hydrochloric Acid and Limestone: Experiment Results

rate of reaction between calcium carbonate and hydrochloric acid results

One of the results of a chemical reaction between calcium carbonate and hydrochloric acid in the stomach is the formation of , which is a type of an ionic salt. 路 I will note down in my table how much gas is in the syringe every 20 seconds for 120 seconds. This should in theory increase the rate of reaction as the temperature is increased. Concentration does not increase the number of successful reactions per second; however both temperature and the use of catalysts, two other independent variables, do increase the number of successful reactions per second. The concentration of acid remained the same throughout the preliminary experiment because it was the values for the constants that we are finding out. So temperature and surface area will be kept constant, no catalyst will be used and the concentration of hydrochloric acid will be the variable.

路 I will set up the clamp stand and gas syringe. Conclusion The rate of reaction graph has a positive correlation between the rate of reaction and the concentration; however the line of best fit is not linear but curved. Method 3 was not feasible as the scales we had available were not accurate enough for our experiment. 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. Additionally the amount of carbon dioxide given out can me measured accurately and fairly quickly.

How the concentration of hydrochloric acid affects the rate of reaction between calcium carbonate and hydrochloric acid

rate of reaction between calcium carbonate and hydrochloric acid results

Concentration - Concentration effects the rate of a reaction because the higher the concentration of particles the. Take one large piece of Calcium Carbonate and record its weight. 路 I will note down in my table how much gas is in the measuring cylinder every for each test. Prediction: I predict that when I increase the temperature of the hydrochloric acid the reaction will take place quicker so more gas will be produced in a shorter amount of time. Therefore I made the following changes to my method: 1. Therefore the quicker the reaction.

I chose not to keep the concentration constant because it is easy to change and in comparison to these three other variables I think that it will be the quickest and most accurate variable. Furthermore the chips were dropped in the conical flask and the bung was immediately placed on the flask while the stopwatch was started. Explain this using the particle collision theory. It is more likely to occur in areas, where there is more pollution. The reaction produces a gas, carbon dioxide. As I repeated the experiment 3 times and worked out the average rate of reaction in each test, I think my results are quite reliable. Also I think that my results are shown clearly in the graph and table above and reflect the success of my experiment.

For both variables I recorded the time it took for 50cm3 of carbon dioxide gas to be produced. We took the 25cm鲁 of 0. Evaluation: I think that the method I used got me accurate and reliable results as you can see by the fact that they matched my prediction and I did not really have any anomalous results I think my results were accurate because I carried out my experiment with care repeating the experiment twice and measuring out my substances carefully and accurately. Increasing the concentration of a solution leads to more collisions greater frequency of collisions so the rate of the reaction goes up. When two reactants collide together and form a new. Form a seal over the bottom of the tube and plunge it into the water bath making sure that no bubbles get into the tube and effect the reading on the tube.
