A beaker contains 0.10M silver ions, 0.01M zinc ions, and 1.00M aluminum ions. Solid sodium cyanide is then added slowly (assume no volume change). The Ksp for silver cyanide is 1.2x10^-8, the Ksp for zinc cyanide is 8.0x10^-12, and the Ksp for aluminum cyanide is 2.3x10^-21. What is the minimum cyanide concentration needed to precipitate each condition?
