In many patients, it may also be advisable to take this supplement in order to increase the amount of calcium in the body or to prevent loss of bone mass. One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction. The line which represented the amount of gas given off on the graph was steeper in the test using powder therefore the gas was produced at a faster rate. Some generous chemists will prepare a 10% solution for you. I want to find out how different strengths of acid affect the speed of the rate of reaction.

Rates of Reaction: Hydrochloric Acid + Calcium Carbonate

the reaction between calcium carbonate and hydrochloric acid

From this equation, it is evident to us that hydrochloric acid has a large effect on the reaction. Acid dispensing bottles: Small acid dispensing bottles work well for the acid test. A list of common and occasionally encountered carbonate minerals is given in Table 1 with their chemical composition and their relative reaction with cold and warm hydrochloric acid. Scientific knowledge: Marble chips erode when they are exposed to acid rain or pollution. Hydrochloric acid and calcium carbonate:. 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. That will reduce the amount of frivolous acid use that might otherwise occur.

Hypothesis: The more concentrated the substance, the greater chance of the Hydrochloric Acid there is to collide with the Marble chip giving a more produced; carbon dioxide. 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. 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. Small, nearly empty bottles makes less acid available to spill. If the particles collide fast enough and in the right direction, sufficient energy to break these bonds will be produced the activation energy , which will allow the reaction to take place.

This is probably down to human error, as there was no large difference in temperature that day. Another easy way to produce a small amount of mineral powder is to scratch the specimen with a nail. It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. As the carbon dioxide escapes to the air, of the flask and its contents will decrease. This description is for one drop of acid. Patients with conditions that include elevated levels of calcium should check with a doctor before using calcium carbonate as a treatment for excessive hydrochloric acid in the stomach. Middle I think that the less concentrated the hydrochloric acid is the longer it will take for it to react with the calcium carbonate.

· I will note down in my table how much gas is in the syringe every 20 seconds for 120 seconds. To keep the acid test from fouling your entire collection, ask students to rinse specimens after testing with acid and limit testing to only when it is needed. He began writing online in 2010 with the goal of exploring scientific, cultural and practical topics, and at last count had reached over a hundred million readers through various sites. The other main control variable was human error, which we could control by taking our time, not hurrying and staying focused during our experiment. The carbonate group is actually covalently bonded carbon and oxygen, but the calcium carbonate as a whole is ionic.

Seek prompt medical attention for eye contact. In our experiment the independent variable would be the concentration of hydrochloric acid, the dependent variable would be the amount of carbon dioxide, and the main variable which we had to control was the reading of carbon dioxide in the cylinder. I believe that 10 repetitions would be a good amount, as it would be easier to identify outliers and you would get a more accurate average. 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. Therefore the quicker the reaction. The mineral reacts with hydrochloric acid to produce carbon dioxide gas, water, a dissolved metal ion, and dissolved chlorine.

Titration of Sodium Carbonate With Hydrochloric Acid

Instead of seeing an obvious fizz, you will see a drop of acid on the surface of the mineral that might have a few bubbles of carbon dioxide gas slowly growing on the dolomite surface. This is because I think the more obvious reaction would have been clearer and would demonstrate the patterns and trends of the data more effectively. Additionally I predict that the volume of hydrochloric acid used in the main experiment will be 20 or 25cm3 because similarly it will give a time not too long but not too quick. Prediction: I predict that the heating the hydrochloric acid will effect it as heating is one… 2295 Words 10 Pages Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. I did not choose the variable to be temperature because it is difficult to maintain and requires precise measurements. Hcl is a gas that has to be mixed with water into a concentration. · I will set up the clamp, stand and measuring cylinder.

Investigating the Rate of Reaction Between Marble Chips...

However, I could make further improvement by increasing the number of tests and taking the results with a smaller gap such as 10 seconds instead of 20. In fact, the only thing that could have been improved would be how quickly I fastened the bung and started the timer but this was very hard there was a lot to do in that very short time span. I believe that concentration affected the rate of reaction in this way as explained in collision theory. Concentration of the acid is higher so there is more chance of the particles colliding. Another reason why the rate increases is that some colliding particles just ‘bounce' off each other; they cannot ‘bang' hard enough to create a reaction due to there being not enough energy.
