The objective of the Unknown White Compound experiment was to investigate the compound’s physical and chemical properties to correctly identify and then synthesize the compound. The first step was to test the compounds solubility and create a solution with distilled water. Next, a pH test was conducted by testing the unknown compound using pH paper. Following, the flame test was used to determine the cation and the ion test was used to determine the anion, which concluded the compound to mostly be potassium nitrate. Next, a conductivity probe and pH probe were used to confirm the unknown compound to be potassium nitrate. The final step was to synthesize potassium nitrate using silver nitrate and potassium chloride. The experiments listed above concluded the unknown white compound to be potassium nitrate. Interestingly, the work’s main goal is to follow lab safety and properly dispose …show more content…

Many unknown micro-contaminants are present in water. Some of the micro-contaminations might pose a risk to drinking water and human health. In many countries, surface water is one of the main sources of drinking water. The quality of the drinking water is influenced by many factors, such as agricultural and industrial waste, and is monitored regularly. Stated by the Journal of Chromatography, there are many techniques such as gas and liquid chromatography in order to detect the pollutants. However, there are many unknown compounds present in water, which could pose health risks if not removed. Identification of unknown compounds is based on comparison of the mass spectra of the peaks in the sample with mass libraries or interpretation of the fragmentation. The identification of water contaminations is interesting and similar to the Unknown White Compound lab by making comparisons to other compounds to help identify the
