Science and Technology - Laboratory Course (SCI103-1404A-04) - Lab Report Example d 3 appear to be more acidic due to the fact that they are located on the downwind direction from the lake described as 1 which is surrounded by an industrial and settlement area. Carbon (iv) oxide and sulphur (iv) oxide are emissions associated with industrialization and are carried downwind by the wind and fall end up falling as acid rain. Lake 2 is found to suffer most from acidity as it is said to have a higher elevation as compared to Lake 3. Acidity falls in the form of either snow, rain or fog. The pH scale usually has a range running from 0-14. A pH value that is equal to 7 is said to be neutral. A pH value that is less than 7 is said to be acidic in nature and a pH that is greater than 7 is said to be basic. The PH scale is normally used to measure the concentration of hydrogen ions that is present in a solution. A low pH usually represents solutions that have a high concentration of hydrogen ion while high PH usually represents solutions with low concentration of hydrogen ions. Acids on a PH scale are substances that when added to water increases the concentration of hydrogen ions thus lowering the PH. A base on the other hand usually lowers the concentration of hydrogen ions thus raising the PH. There are other substances called buffers that enable solutions to resist changes in
