Introduktion
The idea behind this investigation began when we were learning about the acidic nature of rainwater which was due to the dissolved carbon dioxide in the atmosphere, pure rainwater is naturally acidic with a pH of 5,6.
Rainwater is associated with acid rain which is one of the most important environmental issues that is caused as a result of air pollution, all rainwater is considered to be slightly acidic because it contains some dissolved carbon dioxide.
The oxides of sulfur and nitrogen are the major sources of atmospheric acidity, these oxides are the products of combustion reactions and are both converted to strong acids in the atmosphere.
When I once traveled to London, I used to hear people refer to London as the city of fog, so I started questioning the reason behind this and it turned out that London was given that nickname because of the huge quantities of air pollutants which were produced by its factories.
This intrigued my interest and I started to wonder about the effects of acidic deposition on the environment and health, but what intrigued me the most was the influence of acid rain on buildings and the sculptures that we see in our daily lives.
I, therefore, wanted to explore how acid rain affected buildings and statues, so I decided to construct a model that illustrated the influence of sulfuric acid which is one type of acid rain on the rate of corrosion on limestone, this was done by using different concentrations of sulfuric acid and observing their rate of reaction with calcium carbonate which was a model for limestone.
The effect of the different concentrations of sulfuric acid was observed by analyzing how the increasing molarity affected the rate of mass loss of calcium carbonate.

Predictions
Hypothesis: As the concentration of sulfuric acid increases, the rate of reaction with calcium carbonate will increase hence the rate of mass loss of gas increases, this is because of the fact that as the concentration increases there will be more particles produced per volume, which will lead to more frequent collisions and hence a higher rate of reaction.
Null hypothesis: As the concentration of sulfuric acid increases, the rate of reaction with calcium carbonate will not increase.
