Thermal decomposition of metal carbonates

thermal decomposition of copper carbonate experiment

To acquire the proper techniques of carrying out a titration. However, the metal carbonate that thermally decomposed the slowest releasing the least carbon dioxide was Sodium Carbonate. As the carbonate is heated it will take longer for carbon dioxide to be given off because the bond that Potassium has with its carbonate is very strong. Maintaining the same temperature throughout all the metal carbonates is crucial so that the experiment is fair. From the equations above we can see that… 2788 Words 12 Pages Investigating the rate of electrolysis.

The carbonate was heated with a roaring flame and began to both turn black and reduce in volume. Assuming the presence of errors, the whole cylinder could result in being completely empty. Measure out lime water and clamp boiling tube on to stand. Experiment 3 Fill the water bath, allowing room for at least an extra 100ml of water. These aquatic plants can produce an enormous amount of carbon dioxide into the ocean due to decomposition.

To understand the concepts is only possible with investigating the temperature distribution in biological tissue. Calcium reacts slower as it is placed in cold water. This will keep my test fair as I will always be testing the carbon dioxide which is produced for the atomic mass of each metal carbonate. Preliminary experiment Limewater and copper were used to see if a carbonate beaks down to produce. Apparatus --------- 1 Gas syringe measured in millilitres ml 2 Stop Clock 3 A set of scales weighed in grams g 4 Zinc, magnesium, copper, calcium and chorine metal carbonate 1 mole 5 5 test tubes 6 Delivery tube 7 Bunsen burner 8 Heat proof mat 9 Clamp 10 Ruler My apparatus was set up as in the diagram.

The exothermic reaction provides enough energy for heavier chemical elements to be made by the process of nucleogenesis. These molecules or ions are functioning as ligands electrophile in organic compounds. Put the Bunsen burner on a blue, non-roaring flame, and heat the bottom of the boiling tube. Several metal carbonates were placed in a test tube and linked to a syringe that measured the amount of carbon dioxide gas when the metal carbonates were heated. Hydrogen is also given off by the potassium as it reacts with the cold water.

These factors can make the results of the experiment be incorrect. This will make it easier to be thermally decomposed. Carbonic acid is unstable, decomposing to give carbon dioxide gas and water. The experiment should take about 40 - 45 minutes. Pyrolysis is a chemical test, meaning particles go through a process of being dried by increasing heat to extremely high temperatures which finalize the result for identification or specific findings. As you can see from the diagram in one tube there was limewater that was to test for the carbon dioxide, and in the other was copper carbonate. This could be an anomalous result because the Sodium Carbonate was contaminated with a metal higher up in the reactivity series.

This ensures that the flame can be seen and it is cooler than the blue flame. If equation 2 is correct I expect the collected volume of gas to be about 38. Calcined heated dolomite is extensively employed as a lining for Bessemer converters in the production of steel from pig iron. Although this is a good way of checking if carbon dioxide is present it is totally irrelevant in my experiment. Experiment 3 Fill the water bath, allowing room for at least an extra 100ml of water. In this experiment there are a few factors that can affect the results of the experiment.

The new substance is a black powder. My results are fairly accurate as they have been in a lab. Investigation of the Thermal Decomposition of Copper Carbonate Aim: Copper has two oxides, Cu2O, and CuO. If the metal is unstable its bond with the carbonate will be weak. The mass of the metal carbonate will remain constant through out all the experiments; the distance that the metal carbonate will be away from the flame will be the same. There are also, however, misconceptions of a particular genre, that many overlook; metal music. Experiment 4 Fill the water bath, allowing room for at least an extra 100ml of water.

The flame should be at a blue flame, but not roaring, as this can break the boiling tubes, broken glass is a hazard. This means using the same Bunsen burner on the same setting on the same gas tap for each experiment. In this experiment, Hess's law will be utilized to calculate the decomposition of Calcium carbonate. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures. It is made mostly of. It is vital to all life on Earth. She also helped observe the grass.
