How many grams of potassium iodide should she add

Reference no: EM13171884

a reseacher has a 100.0 mL solution that is 0.491 M in Hg2(No3)2 and 0.0294 M in Pb(N03)2. She plans to add solid potassium iodide to separate the mixture by selective precipitation. Ksp PbI2=1.4e-8, Ksp Hg2I2= 1.2e-28
What is the maximum concentration of iodide ions that may be in solution to achieve the best separation possible?
How many grams of potassium iodide should she add to achieve this?
What will the percentage of mercury (I) ions remaining in solution be?
