QUESTION 11
Determine the molar solubility of MX (Ksp 8.3x108) in 0.748 M NaCN. The metal ion M forms M(CN)2 (K-2.1x10) in the presence of CN ion, Enter
your answer in scientific notation with two significant figures. For example, 0.001357 would be entered as 140-3
QUESTION 12
The metal ion M²+ in ammonia, NH3 forms the complex ion M(NH3)62+ (K= 6.4x1012). Calculate the M2+ concentration when the equilibrium
concentrations of NH3 and M(NH3)62+ are 0.065 and 0.43 M respectively. Enter your answer in scientific notation with two significant figures. For
example, 0.001357 would be entered as 1.4e-3.
