5. When copper sulfate is dissolved in water, it forms a clear blue solution. What are the formulas of the two ion in this solution? A small amount of aqueous ammonia is added to this solution, and a light blue precipitate forms. What is the formula for this precipitate? The precipitate dissolves to form a dark blue solution when more ammonia is added. Why?

The ion Hg2+reacts with chloride ions to make the complex HgCl4 2- , which has a Kf = 1.1x1016. In a solution after the reaction is complete the concentration of HgCl4 2- = 0.032 M and the concentration of chloride ions is 0.83 M. Calculate the equilibrium concentration of uncomplexed Hg2+ in this solution.

Barium fluoride has increased solubility in acidic solution. Why?
When species combine to produce a coordination complex, the equilibrium constant for the reaction is called is the formation constant, Kf.For example, the iron(II) ion, Fe2+, can combine with the cyanide ion, CN−, to form the complex [Fe(CN)6]4− according to the equation Fe2+(aq)+6CN−(aq)⇌[Fe(CN)6]4−(aq) where Kf=4.21×1045.This reaction is what makes cyanide so toxic to human beings and other animals. The cyanide ion binds to the iron that red blood cells use to carry oxygen around the body, thus interfering with the blood's ability to deliver oxygen to the tissues. It is this toxicity that has made the use of cyanide in gold mining controversial. Most states now ban the use of cyanide in leaching gold out of low-grade ore. The average human body contains 6.30 L of blood with a Fe2+ concentration of 2.50×10−5 M . If a person ingests 9.00 mL of 12.0 mM NaCN , what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
Cu2+ mixed with OH- ions in water forms the blue precipitate Cu(OH)2(s). Cu2+ mixed with a small amount of NH3 in water also forms the same blue precipitate Cu(OH)2. Explain how this happens.
Dilute sodium cyanide solution is slowly dripped into a slowly stirred silver nitrate solution. A white precipitate forms temporarily but dissolves as the addition of sodium cyanide continues. Use chemical equations to explain thisobservation. Silver cyanide is similar to silver chloride in its solubility.
