<u>Calcium carbonate:</u>
The calcium carbonate is found in sea shells and the bones of sea creatures. And it is settled on layer of ocean. The pH level can be equilibrium with atmospheric 
. There is constant concentration of in the water.
The limestone and calcium carbonate is present in the rocks, streams, lakes is helps to maintain the constant pH in the minerals present in the rock react with excess acid in the water.
When the acids or bases react with the calcium carbonate ,there is the excess change in the pH. The mixture of calcium carbonate ions in the water to prevent the damage in acid rain.
<span>The larger the experiment example the more reliable the results would be. Take for example if you analyze something using only 2 examples and one confirms your theory and the other doesn't. That would have you believe that it occurs 50% of the time. If you analyze a hundred of them you can see more correct results. </span>
