The name antacid means anti-acid (against acid). Not only was it a more advanced and more calculated experiment it, the results reflect what I was trying to find out in a clear and exact manor. The rate of reaction increases when the surface area of a solid
The aim of this experiment was to investigate how the surface area affects the rate of a reaction in between calcium carbonate and hydrochloric acid. This reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Discussion: As shown in the graph and table above, each test had a very similar result to the other tests of the same concentration. Premium 5 Pages. -Independent: The molarity of the concentration of Hydrochloric Acid -Dependant: The amount of Carbon Dioxide (Co2) produced per 30 seconds Co2/30s -Controls: Temperature of Hydrochloric Acid, the timing, the amount of Calcium Carbonate chips, gas measurement. This abnormal electrical activity in the brain causes seizures, which may briefly upset a person’s muscle control, movement, speech, vision, or awareness.” My definition of Epilepsy is pretty much the same; however, I would not have used the word briefly as it makes it ... ... concentration of Hydrochloric acid, the amount of gas produced at pre set time intervals, the amount of hydrochloric acid used in each experiment & the amount of calcium carbonate ... ... calcium carbonate that is being analyzed in the experiment. 3 Pages. 4 Pages. Antacids are the primary treatment for ailments such as gastric reflux, gastritis, upset stomach and heartburn. Calcium carbonate cannot be dissolved in water, but can dissolve in an acid using the reaction: Aim. If I was to compare this practical with my last experiment on gelatin I would be majorly impressed. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. I will also mention the time which was taken in the experiment, to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Conclusion: In conclusion, absolutely everything went to plan and not much at all could have been improved. The aim of this experiment was to investigate how the surface area affects the rate of a reaction in between calcium carbonate and hydrochloric acid. affects the rate of reaction by measuring the amount of gas produced
6 Pages. Aim:
3 Pages. Hypothesis: In a reaction between calcium carbonate and hydrochloric acid, the products calcium chloride, carbon dioxide and water are formed. Antacids are defined as a substance, generally a base, which counteracts stomach acidity. I used the scales and measured the Calcium Carbonate to the exact same 0.3 grams every time, I fastened the bung as quickly as I possibly could once the acid had been added and I wrote down my results right on 30 seconds. See INSTRUCTIONS for practical 6.2 & 6.3
Hypothesis. Because, StudyMode - Premium and Free Essays, Term Papers & Book Notes. Hypothesis:
affects the rate of reaction by measuring the amount of gas produced
More than 4% of the Earth’s crust is composed of calcium carbonate. Premium Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. diluted hydrochloric acid. the amount of calcium carbonate in brown versus white chicken eggs. Chips (Calcium Carbonate) and Hydrochloric acid per minute. -Once you have finished testing each concentration, pour the solution through the tea strainer and tap away the Calium on a paper towel. Also concentrations from 0.5m – 2.0 m are each about 3 ml differences whereas the difference between 0.1 m and 0.5 m is almost 5ml. Evaluation: Overall I think that my experiment was a success, form the performance to the results. Calcium Carbonate was solid and Here you can order a professional work.
STANDARDISATION OF HYDROCHLORIC ACID REPORT
This shows how weak the 0.1 m concentration is and if you compared that to a much higher concentration there would be a very large difference. Also I made absolutely sure that I was as accurate as I possibly could be. Chips (, (CaCO3) is a component of seashells and eggshells that gives them their strength and hardness. Finally, I am measuring the amount of hydrochloric acid very carefully and accurately. 3 Pages. Briefly describe your Preliminary Experiment and include your results. Measurement, Mole, Sodium bicarbonate 524 Words | In a reaction between calcium carbonate and hydrochloric acid, the products calcium chloride, carbon dioxide and water are formed. My hypothesis was correct, as the concentration gets higher the reaction creates more Carbon Dioxide per. The higher the concentration of hydrochloric acid, the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. the experiments, which I have done over two weeks. Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables. An increase in concentration ... ... experiment to decompose a carbonate using heat, also to carry out appropriate tests for the formation of products as a result ... and organic materials.
In high concentration acts as ... suggestionsWhile analyzing my experiment results I thought ... period of time, the genetics ... ... Hydrochloric Acid. Sodium, Erlenmeyer flask, Chlorine 1266 Words | 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. In the investigation I am going to find out how the surface area
Hypothesis:
Press F5 key to reload the experiment and this time add a different concentration of acid. Premium Rate of Decomposition of Calcium Carbonate Premium Carbon dioxide, Calcium carbonate, Magnesium 1357 Words | 3 Pages. Limestone and marble have been among the most widely used building materials for more than 5 000 years, from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. Edit the concentration of the hydrochloric acid directly by clicking on the value on the front of the bottle, and typing in a new concentration.
