Answer #1

       AgI(s) --------->Ag+ + I-        Ksp

      Ag+ + 2CN-   -------> [Ag(CN)]-        Kf  

--------------------------------------------------------

over all AgI(s) + 2CN- -----------> [Ag(CN)]-   KC

KsP = 8.3*10-17

K   = Ksp * Kf

     = 8.3*10-17 *5.6*1018     = 4.468*102

large kc value very soluble in NaCN

By now, you all know that silver iodide is very insoluble in water. Chemists know that by adding a very slight excess of silver nitrate to an iodide containing solution it is possible effectively to remove all the iodide ion from the sample. First, write a balanced net ionic equation for this reaction. Then, assume that 2.375 grams of silver iodide were formed on the reaction of the sample and AgNO3. If the % iodide in the sample was 22.50%,...
