Solid KSCN was added to a(2.20x10^0) M Co2+ solution so that it was also initially (2.20x10^0) M SCN-. These ions then reacted to give the complex ion Co(SCN)2+, whose formation constant is 1.0x102. What is the concentration of Co2+(aq) at equilibrium? You may assume x to be small. Express your answer to three significant figures.

Question

Solid KSCN was added to a(2.20x10^0) M Co²⁺ solution so that it was also initially (2.20x10^0) M SCN^-. These ions then reacted to give the complex ion Co(SCN)₂⁺, whose formation constant is 1.0x10². What is the concentration of Co²⁺(aq) at equilibrium? You may assume x to be small. Express your answer to three significant figures.
