The determination of 4.000 mmol of ZnCl2 is performed gravimetrically by the addition of NaCN solution in a Total volume of 200.00ml. Ksp = 3.0X10^-16 for Zn(CN)2. State and verify all assumption. Assume cyanide does not hydrolyze.
a. Derive the COC and COM equations for the solubility of Zn(CN)2.
b. Using the eqution your derive in part (a) calculate the mass loss of Zn(CN)2 if a 10% excess of NaCN is used taking activity into account. Is the mass Loss significant?
