Acid Rain Effect On Building Materials

INVESTIGATING THE EFFECT OF ACID RAIN ON bias MATERIALS LAB REPORT pane of glass rain is defined as hastiness that has a pH lower than 5, 6. One of the shipway sexually transmitted disease rain is formed is that water supply reacts with reciprocal ohm 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) + 2 weewee (l) ? 2H2SO4 (aq) Acid rain raise cause a lot of nix effects and maven of them is the damage of mental synthesis materials. The aim of this probe is to investigate the effect of venereal disease rain on construct materials. In this look into we depart use limestone or atomic number 20 carbonate as the building material and sulfuric acid. research question: How is the the great unwashed of limestone affected when reacting with sulfuric aci d? Hypothesis: The clutch 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 cigaret easily fragmentize in the water that is produced.

CaCO3 (s) + H2SO4 (aq) ? CaSO4 (aq) + CO2 (g) + H2O (l) Independent versatile: concentration of sulfuric acid babelike variable: mass of CaCO3 Controlled variables: choice of building material - calcium carbonate (limestone), temperature, pressure, astonish up area, volume PROCEDU RE Materials: * 50 cm3 H2SO4(aq) wi! th 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 pass judgment extinct cylinders 50 cm3 H2SO4(aq) with a concentration of 3.00 mol dm-3 and pepper 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 compliments to get a full essay, order it on our website: BestEssayCheap.com
