Equal Volumes of a 0

Multiple Choice

Equal volumes of a 0.020 M Zn²⁺(aq) solution and a 2.0 M NH₃(aq) solution are mixed.K_f for [Zn(NH₃) ₄]²⁺ is 4.1 × 10⁸.If enough sodium oxalate is added to make the solution 0.10 M in oxalate,will ZnC₂O₄(s) precipitate? What is Q_sp? K_sp ZnC₂O₄ = 2.7 × 10^-8

A) yes,Q_sp = 11
B) yes,Q_sp = 2.9 × 10^-12
C) no,Q_sp = 2.9 × 10^-12
D) yes,Q_sp = 2.4 × 10^-9
E) no,Q_sp = 2.4 × 10^-9
