Chemical Weathering
Background
Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is excess carbon dioxide causing water to become more acidic, which is essential for chemical weathering. It often occurs more particularly in warmer temperature and close to water, this is essential for reaction to occur easier. An example would …show more content…
Procedure
Using a scale, measure the mass of each of the 6 limestone rocks and write down on the data table.
Using the 200 mL, fill the first beaker with 200 mL of tap water. Set aside.
Fill the second beaker with 150 mL of tap water and 50 mL of carbonated water.
Mix it for 10 seconds. Set beaker aside.
Fill the third beaker with 100 mL of tap water and 100 mL of carbonated water.
Mix it for 10 seconds. Set the beaker aside.
Mix the fourth beaker with 150 mL of carbonated water and 50 mL with tap water.
Mix it for 10 seconds. Set the beaker aside.
Mix the fifth beaker with 200 mL of carbonated water.
Put one limestone rock in each of the five beakers.
Let rocks sit in water for 1 day.
After, remove rocks from the beakers using tongs, place each rock on a separate watch glass, and place them in oven and dry.
Let rocks dry overnight.
Take all 5 rocks, observe them carefully and write down any new observations, like mass, color, and texture and new masses on the data table.
