    Analysis of Alum AlK(SO4)2*12H2O: Determining the Melting Point and Water Hydration PreLab Questions: 1. When measuring the melting point‚ it is best to heat up the sample slowly so that the alum sample would be the same temperature as the water. The sample also needs time to melt. 2. 0.787g Na2CO3 1.336g H2O Moles of Na2CO3 = 0.787/106 = 0.00742moles Moles of H2O = 1.336/18 = 0.0742 Molar Ratio = 10 moles of H2O‚ 1 moles of Na2CO3 Abstract: The purpose
