This kit has been designed to allow the analyst to perform a very simple titration to determine the hardness of their fresh water sample. Water hardness is a measure of minerals such as calcium, magnesium, and iron being carried by the water in solution. These minerals can precipitate out of the water carrying them and form deposits, leading to problems such as scaling in industrial equipment. The titration uses an easily identifiable color transition to indicate the end of the analysis. The kit contains everything an analyst would need to perform a water analysis either in the laboratory setting or out in the field. Kit contains enough materials to perform 40 tests. .
