Phosphate can be harmful when excessive amount is present in the drinking water system. The U.S. Public Health Service has set the maximum value of phosphate in drinking water at 3.0 mg/L. In this experiment, several samples were diluted and its concentration were analyzed through a spectrophotometer. The results obtained (0.1 mg/L and 2.28mg/L) are within the U.S. Public Health Service’s standards and are deemed to be safe.
Introduction
It is important that drinking water is monitored regularly to assure that the quality is within recommend range. Water pollutant can occur in various ways and ingestion of excess minerals (such as phosphate) poses health threats such as gastrointestinal illness, neurological disorders and reproductive issues [1]. Phosphate in drinking water is one of many minerals monitored through solution sampling. Performing a serial dilution process with the use of an indicator and a blank (composed of ammonium vanadomolybdate indicator and distilled water) as a reference, phosphate concentration can be achieved. The aim of this experiment is to determine the concentration of phosphate and to analyze whether its concentration is within the U.S. Public Health Service’s standards.
Methods
In three separate beakers, 5 mL of ammonium vanadomolybdate indicator was dispensed with a volumetric pipette. The ammonium vanadomolybdate indicator displayed the level of phosphate concentration of each solution (darker color indicating the most concentrated). In an…
