QUESTION 11 Determine the molar solubility of MX (Ksp 8.0x109) in 0.012 M NaCN. The metal ion M* forms M(CN)2 (K-9.6x1010) in the presence of CN ion. Enter your answer in scientific notation with two significant figures. For example, 0.001357 would be entered as 1.40-3. QUESTION 12 The metal ion M2* in ammonia, NH3 forms the complex ion M(NH3)2+(K-1.4x1011). Calculate the M2+ concentration when the equilibrium concentrations of NH3 and M(NH3)2+ are 0.086 and 0.76 M respectively. Enter your answer in scientific notation with two significant figures. For example, 0.001357 would be entered as 1.46-3.
