Wanting to form nickel(II) cyanide, Ni(CN)2, a chemist adds
hydrocyanic acid, HCN, to a solution containing Ni2+ ions hoping to
precipitate Ni(CN)2. The important equlibria for this process are
given below: HCN(aq) <--> H+(aq) + CN-(aq) Ka=4.0x10^(-10)
Ni(CN)2(s) <--> Ni2+(aq) +2CN-(aq) Ksp= 3.0x1-^(-23) a) what
is the equilibrium constant, Knet, for the following reaction which
describes the precipitation reaction the chemist wants to perform?
Ni2+(aq) + 2HCN(aq) <--> 2H+(aq) + Ni(CN)2(s) Knet=????? b)
can the chemist readily form Nickel (II)...
