The Water And Its Effect On The Environment Essay
Water is everywhere, from our oceans to the pond at your local park. These sources like the pond are considered freshwater ecosystem. Water is a neutral compound, meaning that in its natural state, it is neither acidic nor basic and has a pH of 7. However, water is subject to pollution and can easily be polluted by acidic compounds. And when you live in an area with a refinery, the surrounding waters can be very polluted. For this lab, we will test the various freshwater sources around Madison County and determine whether they are polluted or not.
One thing to consider with freshwater is its pH (which is short for power of hydrogen). A water source’s pH can determine whether it is acidic or basic; a pH number above 7 is a basic solution while a pH below 7 is a more acidic solution. When water is more acidic, it has a greater amount of hydrogen ions. However, when it is basic, it has a reduced hydrogen ion concentration due to the hydroxyl ions that the base released when it was dissolved (Kemker, “pH…”). Pure water always has a pH of 7, making it neutral. However, water does not always come in this state and various things pollute it. Rain, for example, can decrease a freshwater source’s pH. Unpolluted rainwater has a pH of 5.6 because to the carbon dioxide in the atmosphere (Acids…). However, this is the pH of the water as it falls. In the atmosphere, it has not come into contact with materials like carbonate or limestone, which are…
