Finding maximum mass...
« on: June 07, 2009, 11:30:38 PM »
Using activity coefficients from Table 8-1 in your text book, calculate the maximum mass of PbI2 which can dissolve in 100. mL of 0.100 M KI?

For this qn, would i have to use an ice table?

Sounds to me like direct application of Kso.

Kso or Ksp - solubility product.

but would I have to use an ice table to find the concentration of I^- at equilibrium?

No, you may safely assume iodide concentration doesn't change end equals 0.1 all the time.
