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?
Determine which ion will precipitate first and at what concentration of sulfate ion will the first precipitate begin to form?
What colligative properties are displayed by these situations.
