2. Potassium alum, synthesized in this experiment, has the formula KAI(SO) 12H:O; written as a double salt, however, its formula is K.SO AL(SO) 24H O. Refer to Table 14.1 and write the formula of ferric alum as a double salt. 3. Answer the following: a. What is the technique for securing a piece of filter paper into a funnel for gravity b. What is the technique for securing a piece of filter paper into a Buchner funnel for c. Why are the alum crystals washed with an alcohol-water mixture rather than with filtration? vacuum filtration? deionized water?
. An aluminum can is cut into small pieces. A 1.16 g sample of the aluminum chips is used to prepare potassiu theoretical yield (in grams) of potassium alum that cou correct number of significant figures. The molar mass of potassium alum is n alum according to the procedure described in this experiment. Calculate the ld be obtained in the reaction using the 474.39 g/mol.
