Question 1 Report

Cu2+(aq) + 4NH3(g) ? [Cu(NH3)4]2+(aq)

In the reaction above, what is the effect of precipitating Cu2+(aq) as CuS(s)?

Answer Details
When Cu2+ is precipitated as CuS, it will be removed from the solution, which will cause the equilibrium to shift to the right to replace the lost Cu2+ ions. As a result, more [Cu(NH3)3]4+ will be produced to compensate for the loss of Cu2+ ions. Therefore, the correct option is "The equilibrium will shift to the right."
