Hydrochloric acid is used in medicine, industry, and chemical reactions. Here you can order a professional work. CaCO₃ is a widespread compound found in chalk, lime, marble, and more. It is also popular in the food industry as a natural white colorant. The digestive tract eliminates the carbon dioxide as a gas. Calcium carbonate precipitates: Calcium oxide, also known as quicklime or burnt lime, is commonly used in construction. Hypothesis: Aluminum is the most reactive with acids because it occurs in group III. The most they differed by was 1.5 ml of water displaced. I will use the same method with the hydrochloric acid 0.1 molar, 0.5 molar, 1.0 molar, 1.5 molar, 2.0 molar. Explain how these results have helped you plan your main experiment (p8b). You must cite our web site as your source. Hydrochloric acid reacts with calcium carbonate to produce calcium chloride, carbon dioxide and water. Also I made absolutely sure that I was as accurate as I possibly could be. In high concentration acts as ... suggestionsWhile analyzing my experiment results I thought ... period of time, the genetics ... ... Hydrochloric Acid. In industry, the calcium oxide needed for the above process is produced via calcination. When treated with sulfuric acid, dolomite yields calcium sulfate (gypsum) and magnesium sulfate (Epsom ... ... result Dependence variable: Purity of calcium carbonate in egg shell Controlled variable: Concentration of Hydrochloric acid Uncertainty and error: Measuring ... experiment because of the strong hydrochloric acid In case, if there is an acid ... Molar ratio ... All Papers Are For Research And Reference Purposes Only. Briefly describe your Preliminary Experiment and include your results. No spam – just awesome science news once a week. If limestone or marble is heated to a temperature of 900-1000°C, the resulting chemical processes yield carbon dioxide and the desired calcium oxide CaO: But if the temperature is even higher (1500°C) and a carbon source is present, the reaction will produce calcium carbide and carbon monoxide: Hydrochloric acid is a strong monobasic acid and is obtained via the dissolution of hydrogen chloride HCl in water. When the CaCO3 was added to HCl, they react to produce Calcium Chloride (CaCl2), Carbon Dioxide (CO2) and water (H2O). 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. Let’s talk a little about the interaction between hydrochloric acid and calcium carbonate, and the nature of these compounds themselves.

Hydrochloric acid can also be obtained from the secondary gases released in a number of chemical processes, such as when hydrocarbons are chlorinated. You've already subscribed with this email. Calcium carbonate is a solid white substance that won’t dissolve in it completely: the water will turn a muddy color and a white precipitate will appear. calcium carbonate is a chemical compound with the formula CaCO3. If I was to test this experiment again, the only thing that I would change would be to use higher concentrations of Hydrochloric Acid. Chemical reactions with metals are mainly accompanied by the release of hydrogen, the intensity of which depends on the activity of the metal. 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. Hydrogen chloride gas dissolves in water. 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. For example, the alkaline metal lithium reacts violently, while aluminum reacts only weakly due to its durable oxide film. Conclusion: In conclusion, absolutely everything went to plan and not much at all could have been improved.
