Question

I. An alum is a double salt consisting of a monovalent cation, a trivalent cation, and two sulfate homs with 12 waters of hydration (waters of crystallization) as part of the crystalline structure . Are the 12 waters of hydration used to calculate the theoretical yield of the alum? Explain. b. The 12 waters of hydration are hydrated (strongly attracted) to the metal ions in the crystalline alum structure. Are the water molecules more strongly hydrated to the monovalent cation of the trivalent cation? Explain. hat might you expect to happen to the alum if it were heated to a high temperature? Explain e. W ium alum, synthesized in this experiment, has the formula KAI(So) 12 H,O: written as a double salt, however, its formula is K SO Al(SOJ24 H.O. Refer to Table 15.1 and write the formula of a. chrome alum as a double salt. b. ferric alum as a double salt. 11c a. Experimental Procedure, Part A.3. What is the technique for securing a piece of filter paper into a i funnel for gravity filtration? Experiment 15 71
