A solution is prepared by mixing 50.0 mL of 0.50 M Cu(NO3)2 with 50.0 mL of 0.50 M CO(NO3)2- Solid sodium hydroxide is then slowly added to the mixture. Assume no change in volume occurs. Ksp = 2.2 x 10-20 M³ for Cu(OH)2, Ksp = 1.3 x 10-15 M³ for CO(OH)2 If you use exponents, it should be entered as follows; 1.00 x 10-14 is entered as 1.00e-14. Determine the following from the above information: The hydroxide ion concentration at which the first metal hydroxide will just begin to precipitate is M. Use the integer designators (1, or 2) to answer the following question. The metal hydroxide that precipitates first is {(1) Cu(OH)2 or (2) Co(OH)2} = M. The hydroxide ion concentration at which the maximum amount of the first cation is precipitated while leaving the second cation completely in the solution. is = M. The percentage of the least soluble metal ion that remains in the solution is %

Question 18 A solution is prepared by mixing 50.0 mL of 0.50 M Cu(NO3)2 with 50.0 mL of 0.50 M CO(NO3)2- Solid sodium hydroxide is then slowly added to the mixture. Assume no change in volume occurs. Ksp = 2.2 x 10-20 M³ for Cu(OH)2, Ksp = 1.3-x 10-15 M³ for Co(OH)2 If you use exponents, it should be entered as follows; 1.00 x 10-14 is entered as 1.00e-14. Determine the following from the above information: The hydroxide ion concentration at which the first metal hydroxide will just begin to precipitate is = M.
