Unformatted text preview: Suppose you were not able to discount the importance of AgX 2 when calculating the solubility of AgX in distilled water, where X is a singly charged anion. Show how you would carry out the calculation in this situation by (a) writing an equation that can be solved for the [Ag + ] and writing an equation for the solubility of AgX that is a function of [Ag + ]. In your solution, assume the following reactions: AgX (s) Ag + + X K sp Ag + + X AgX (aq) K 1 AgX (a) + X AgX 2 K 2 3. Calculate the ionic strength of the following solutions that contain the same molar concentration of chloride ion: 0.30 M NaCl, 0.15 M CaCl 2 , and 0.10 M AlCl 3 . 4. Calculate the concentration solubility product ( K sp c ) for Zn 2 [Fe(CN) 6 ] in a solution of 0.010 M Mg(NO 3 ) 2 . 5. Calculate the solubility of Zn 2 [Fe(CN) 6 ] in 0.010 M Mg(NO 3 ) 2 and compare to its solubility in distilled water (see problem 1 of takehome assignment 4)....
