What is the maximum concentration of iodide ions that may

Reference no: EM13644361

A researcher has a 500.0 mL solution that is 0.322 M in Hg2(NO3)2 and 0.0104 M in Pb(NO3)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

a)What is the maximum concentration of iodide ions that may be in solution to achieve the best separation possible? (It will be 1.2e-3)

b)How many grams of potassium iodide should she add to achieve this?

C)What will the percentage of mercury(I) ions remaining in solution be?
