Acid Rain Effect On Building Materials

INVESTIGATING THE EFFECT OF ACID RAIN ON twist MATERIALS
LAB REPORT

Acid 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 sulfur 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) + 2H2O (l) ? 2H2SO4 (aq)
Acid rain raise cause a lot of negative effects and maven of them is the damage of building materials.
The aim of this investigation is to investigate the effect of acid rain on building materials. In this look into we depart use limestone or calcium carbonate as the building material and sulfuric acid.
Research question:
How is the the great unwashed of limestone affected when reacting with sulfuric acid?
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 calcium carbonate, calcium sulfate is formed. It is alcohol-soluble in water and therefore can easily fragmentize in the water that is produced.




CaCO3 (s) + H2SO4 (aq) ? CaSO4 (aq) + CO2 (g) + H2O (l)
Independent versatile: concentration of sulfuric acid
Dependent 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 measure extinct cylinders 50 cm3 H2SO4(aq) with a concentration of 3.00 mol dm-3 and pour 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 want to get a full essay, order it on our website: Orderessay
