Introduction Testing and analyzing the quality of water can be used to determine if the water is safe or not to ingest. Some tests performed on water will help determine if the water is bacteriologically free, contains chemical contaminant such as nitrates, the acidity of the water itself, or to see the amount of chloride in water. Hydrology is the study of water. It has evolved as a science due to the need of understanding the complex water system and to help solve water problems (USGS). In this lab, a series of titration were conducted in order to see the amount of calcium present in different samples of water in the state of Florida. Measuring the amount of calcium in water determines how hard the water is. Hard water is water that is high in dissolved minerals such as calcium and magnesium. When water moves through the soil and rocks, it dissolves small amounts of minerals and holds them in the solution. (Water Research Center 2015). Multiple samples of water, such as different brands of bottled water, as well as tap and deionized water will undergo different trials of titration as well as measuring the conductivity of each sample in order to see the amount of calcium present. By doing this, it will show how pure the water is and whether it has an impact on people’s health.
