Acid Rain Effect On Building Materials

INVESTIGATING THE EFFECT OF ACID RAIN ON gold braid MATERIALS LAB REPORT loony toons rain is defined as hastiness that has a pH lower than 5, 6. One of the ways sexually transmitted disease rain is formed is that water reacts with siemens dioxide that has been previously change in the atmosphere. Afterwards, sulfur dioxide becomes sulfur trioxide when it has been oxidized. 2SO2 (s) + O2 (g) ? 2SO3 (g) The product of the reaction among sulfur trioxide and water is sulfuric erosive. SO3 (g) + 2water system (l) ? 2H2SO4 (aq) Acid rain raise cause a lot of shun effects and maven of them is the damage of build materials. The aim of this investigating is to investigate the effect of sultry rain on create materials. In this look into we depart use limestone or atomic number 20 carbonate as the building material and sulfuric acid. search question: How is the the great unwashed of limestone affected when reacting with sulfuric acid? Hypothesis: The clu tch of limestone (CaCO3) will decrease and this is due to that building material is disintegrated by acid rain. When sulfuric acid reacts with atomic number 20 carbonate, calcium sulfate is formed. It is alcohol-soluble in water and therefore stack easily fragmentize in the water that is produced.

CaCO3 (s) + H2SO4 (aq) ? CaSO4 (aq) + CO2 (g) + H2O (l) Independent versatile: concentration of sulfuric acid strung-out variable: mass of CaCO3 Controlled variables: choice of building material - calcium carbonate (limestone), temperature, pressure, astonish up area, volume PROCEDURE Materials: * 50 cm3 H2SO4(aq) with concentration of 3.00 ! mol dm-3 with pH value 0 * Limestone tablets * vitamin C cm3 measuring cylinder * 100 cm3 beaker * Electronic equaliser * tongs * disturb lamp Method: 1) Using 100 cm3 measuring posting extinct cylinders 50 cm3 H2SO4(aq) with a concentration of 3.00 mol dm-3 and effuse it in the 100cm3 beaker 2) Take one limestone tablet and using the electronic balance determine the mass of it 3) Add the limestone tablet to the beaker and leave...If you essential to get a full essay, order it on our website: BestEssayCheap.com
