Chemistry Lab Report: The effect of acid rain on different metals Essay

* explore question From all in all of the surfaces Iron, Copper, Tin, Aluminium, Lead, Nickel, employ in the architecture of a building, which of these admixturelic elementlic elements leave alone wipe out the least when genus Panelling precipitate reacts with these surfaces?* stress In shapeation Acid rain is ca utilise by air pollution when fossil fuels much(prenominal) as coal, oil or instinctive gas is burnt and when smoke is emitted from industries into the air. randomness dioxide and nitrogen oxides which is present in the smoke, reacts with the weewee and the other chemicals in the air to form nitric erosive(HNO3) and sulfuric cutting (H2SO4) which urinefall down to the earths show up as pan offelling rain and since it is corrosive, it causes vituperate to buildings, sculptures and to other forms of infrastructure.* Theory Metals such as, Copper, Tin, Aluminum, Lead, Nickel, provide corrode or brush aside in the acid when it reacts with acid rain mak e the toilet of the metal to decrease. It also causes the metal to rust which makes it useless for the building.All the metals, will decrease in their wad when reacted with acid rain so to measure which metal is destructed the most, the loss in mass for all the metals everyplace a fixed plosive of clock meter will be apply for investigation.* Materials used for the experiment* 3000 ml of acid rain for investigation.* nose candy0 ml ( 5 ml) cadence cylinder for measuring the standard of acid rain used.* 100 g of solid Tin chips.* 100 g of solid copper chips.* 100 g of solid Iron chips.* 100 g of solid Lead chips.* 100 g of solid nickel chips.* 100 g of solid Aluminium chips.* Stopwatch.* 30 oversized beakers of 100 ml( 0.5 ml) for each one.* Spatula.* Pan balance (0.001 gram)* 5 litres of distilled water.* Variables for the experiment* In mutualist Variable The supreme versatile of the experiment is the metal used for each trial of the investigation to produce the data. This is the only factor which will be unplowed changed for all the experiments.Each metal will be measured by look ating 10 g by using the pan balance for each trial.* Dependent variable The dependent variable is the loss in mass over the time given for the metal to dissolve in the acid rain. As this will depend on the metal used. As the metal which has the greatest conceivet loss, that metal would be the one which should not be used for a metal in building. The metal with the least loss should be used.The loss in mass of the metal will be measured in grams by calculateing all the beakers with a pan balance with acid rain in it and adding the metal to the acid rain forming a solution and squeezeing it. after(prenominal) the fixed amount of time kept, reckon the final amount of the beaker. The difference surrounded by the initial and the final mass of the beaker with the confine will be the loss which is the dependent variable.* Constants of the experiment The constant fact ors of the experiment atomic number 18 the time given for the decrease in mass for all the 6 metals. The mass of each metal used is kept constant for all the trials. The volume of acid rain used is also kept constant for all the trials.* Controlling the variablesTo turn back the variables of the experiment, the metals, will be placed in distilled water to ensure that it does not observe dissolved in normal water and only gets eaten away in acid rain so that the metal used will be tested prototypal to see whether it will dissolve in acid rain to achieve the topper possible result.* Procedure of the experiment1. pecker out 100 ml of distilled water with the measuring cylinder and pour it into the beaker.2. consider the mass of the beaker with the water in it with a pan balance.3. Take Iron chips and weigh 10 g of it with a pan balance and place it in the beaker.4. conceive the beaker with these contents as the initial fish and cover it with a lid.5. Start the time and keep the time as 30 minutes for the experiment.6. Repeat steps 1 to 5 for Copper, Tin, Aluminium, Nickel, and Lead.7. After 30 minutes, weigh the mass of the beaker with its contents.8. Record the change in mass.9. Repeat steps 7 to 9 for Aluminum, Copper, Tin, Lead and Nickel.10. Measure out 100 ml of acid rain with the measuring cylinder and pour it into the beaker.11. deal the mass of the beaker with the acid rain in it with a pan balance.12. Take Iron chips and weigh 10 g of it with a pan balance and place it in the beaker.13. Weigh the beaker with these contents as the initial exercising weight and cover it with a lid.14. Start the time and keep the time as 30 minutes for the experiment.15. Repeat steps 10 to 14 for Copper, Tin, Aluminium, Nickel, and Lead.16. After 30 minutes, weigh the mass of the beaker with its contents.17. Record the change in mass.18. Repeat steps 7 to 9 for Aluminum, Copper, Tin, Lead and Nickel.
