Please use the values in the resources listed below instead of the textbook values. Sometimes equilibria for complex ions are described in terms of dissociation constants, Kg. For the complex ion Cu(CN)43-, the dissociation reaction is as follows. [Cu*]- (CN"4 Ka- [Cu(CN),) Cu(CN),3- Cu* + 4 CN" - 5.0X 1031 Calculate the value of the formation constant, Ke, for Cu(CN)4.

Explain why addition of NH3 or HNO3 to a saturated solution of Cu(OH)2 in contact with solid Cu(OH), increases the solubility of the solid. O NH3 forms a complex ion with OH-, reducing its concentration and allowing more OH- ions to dissolve from the solid phase. HNO3 reacts with Cu2", thereby reducing the Cu2 concentration and allowing more solid to dissolve O NH3 forms a complex ion with Cu2, increasing the Cu2 concentration. HNO3 reacts with OH-, thereby increasing the OH- concentration and allowing more solid to dissolve O NH3 forms a complex ion with Cu2, reducing the Cu2 concentration and allowing more Cu2 ions to dissolve from the solid phase. HNO3 reacts with OH-, thereby reducing the OH- concentration and allowing more solid to dissolve
