- Abstract
In today’s world, humans have breached several limits in contaminating our already-fragile ecosystems and biospheres, affecting land, water, air, flora and fauna, and producing pollutants in copious amounts due to industrial development, urbanisation and excessive use of fossils fuels due to surging population levels, while wildlife is in sharp decline. Having identified the fact that concentration of dissolved oxygen in water is vital to maintain a health ecosystem in water, the author decides to explore a topic concerning measurements and analysis of certain environmental parameters where chemical knowledge, skills and a problem-solving approach can be employed. This investigation is aimed at determining the relationship between the salinity of water, and its pH value, on the oxygen concentration in regular tap water in Singapore, measured by Winkler method. Observation from the tests, dissolved oxygenis is maximum at extremes of pH, viz 6.40 at pH 5 and 5.64 at pH 9; however, at pH 7, lower levels 4.96 were detected, since the growth of bactericeria leads to the decreased oxygen. Thus, pH>7 or if pH< 7, a high salinity, a lowe qunantity of bacteria, high DO is produces, and low BOD is recorded.
