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...
