Problem: Calculate the equilibrium concentration of Ni2+ in a 1.0-M solution [Ni(NH3)6](NO3)2.

FREE Expert Solution

[Ni(NH3)6](NO3)2→ nitrates are soluble

[Ni(NH3)6](NO3)2(aq)[Ni(NH3)6]2+(aq) + 2 NO3-(aq)


Ni2+(aq) + 6 NH3(aq) [Ni(NH3)6]2+(aq)

Kf [Ni(NH3)6]2+ = 5.5×108


Construct an ICE chart:


Kf=[NiNH36]2+[Ni2+][NH3]65.5×108=1.0-x(x)(6x)6
