A solution is prepared by mixing 50.0 mL of 0.050 M Cu(NO3)2 with 50.0 mL of 0.25 M Co(NO3)2. Sodium hydroxide is added to the mixture. a) Determine which metal hydroxide compound will precipitate first based on the provide Ksp values below. (3 pts) b) What should be the minimium concentration of hydroxide ions to cause the precipitation of compound in part a. (7 pts) (Hint: setup the dissociation reactions and Ksp expressions)
