Thermal analysis of zoledronic acid hydrate introduction zoledronic acid (or zoledronate) is a drug substance (api) that is used in different pharmaceutical products such as zometa® or aclasta® to treat osteoporosis (bone diseases) and bone metastases. Chm 1025c/chm 1032c chm 1025c/chm 1032c experiment #8 determining a mole ratio: hydrate analysis lab objective/goals: you will use techniques of quantitative analysis to determine the percent by mass of water in a solid and the formula for water of hydration (or hydrate. A salt with associated water of crystallization is known as a hydrate the structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures   historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the composition. This hydrate was previously mentioned in class to be magnesium sulfate heptahydrate thus, the ratio between water and magnesium sulfate will be close to being 7:1 data & analysis.
1 determine the mass percent sulfate and precent water in an unknown metal sulfate hydrate, 2 carry out composition and reaction stoichiometry calculations, 3 identity of the metal in the unknown metal sulfate hydrate, 4 gain experience in gravimetric lab techniques and the use of a crucible 5 determine the formula of the unknown metal sulfate hydrate. Hydrates analysis objective: the formula for an unknown hydrate is quantitatively determined by heating the unknown hydrate to constant mass and calculating the ratio of the moles of water to the moles of anhydrous material observations will be made of any color changes during heating and re-hydration of the compound as well as heat effects. Analysis the accurate characterisation of hydrated crystal forms is of foremost importance for the chemical industry only when the stability and behaviour of the hydrate are known and understood, is it safe to manufacture. Properties of hydrates objectives • identification of hydrates in a group of compounds • investigation of the properties of hydrates • determination of the number moles of water of hydration in a hydrate background water, the most common chemical on earth, can be found in the atmosphere as water vapor.
