4.30. Using solubility rules, predict the solubility in water of the following ionic compounds. a. AI(OH) b. CaN C. NH4CI d. KOH 4.32. Using solubility rules, decide whether the following ionic solids are soluble or insoluble in water. If they are soluble, write the chemical equation for dissolving in water and indicate what ions you would expect to be present in solution. (NE SO b. BaCO c. Pb(NOs)2 d. Ca(OH) 4.34.

6 6. Zinc hydroxide, Zn(OH)2. is practically insoluble in pure water. (Kap 3.0 x 10-16) a) Determine the pH of a saturated aqueous solution of Zn(O1H)2. (You should assume that all hydroxide ions in the solution come from the Zn(OH)2: you can ignore the autoionization of water.) (4 pts) b) Zn(OH)2 is less soluble in even very dilute solutions of Zn(NOs)2 due to the common ion effect. Determine the molar solubility of zine hydroxide in a 1.0 x 10-4 M...

5.) Solid silver bromide , AgBr, can be dissolved by adding concentrated aqueous ammonia to give the water- soluble silver-ammonia complex ion. AgBr(s) + 2NH,(aq) U Ag(NH), (aq) + Br(aq) (a) Show that this equation is the sum of two other equations, one representing the dissolution of AgBr into its component ions and the other representing the formation of the silver-ammonium complex from silver ion and ammonia (b) Calculate the equilibrium constant for the above reaction K,(AgBr) =...
