The following problems all deal with the same situation described below. As you probably know (and as we have discussed in class), water is a polar molecule with partial charges o = 6.439 x 10-20 C. Imagine a simplified model of an aqueous Cast solution: a single Cast ion and a single H20 molecule sitting in a vacuum (SO E = 60 = 8.85 x 10-12 C2 N.mz). According to the reference below, the typical distance between the oxygen and the Cast ion is 9.2 pm (1 pm = 1 x 10-12 m). From the properties of the water molecule, this means that the Cast ion is 101.7 pm from each hydrogen. The masses for each are also given in the table below. 101.8 pm - - - Molecule/lon Mass [kg] Ca2+ 6.66 x 10-26 Ca2+ -28 9.2 pm HO 2.99 X 10-26 +8 Jalilehvand, F., D. Spangberg, P. Lindqvist-Reis, K.
