Chemistry

Hello, this is for my analytical chemistry class. How do yousolve the following question: Calculate the solubility ofPb(IO3)2 in a solution of 0.020MMg(NO3)2 using activities. Assume that sincePb(IO3)2 is only sparingly soluble that itdoes not contribute to the ionic strength. Please use the extendedDebye-Huckel equation. αPb2+ = 450pm αIO3-​ =450pm Pb(IO3)2 Ksp =2.5*10-13

Thank you.

Since PbIO32 is only sparingly soluble we will assume that we can ignore its contribution to the ionic strength thus It is possible to calculate activity coefficients using the extended DebyeHckel equation logA051zA2133A69136913logA051zA2133A Equation 1 where zA is the ions charge A is the effective diameter of the hydrated    See Answer
