percentage by mass of water in Epson salt? DISCUSSION- When a crystal forms from water solutions‚ it takes a certain amount of water as part of the crystalline structures. The water is not covalently bonded to the host molecule or ion. Water is taken up in definite proportion in relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization

The Importance of Chemistry in Life and Society Michael Birzon University of Phoenix February 28‚ 2013 The Difference Between Accuracy and Precision In the fields of mathematics‚ chemistry and all sciences accuracy can and or is defined‚ as a form of measurement‚ which calculates the degree of closeness of a quality to the quality’s truest value. While on the other hand‚ precision is a form of measurement that is exact‚ but is one in which can be duplicated and reproduce the same results
