1for the given q the ans of mithun is quite right for sure otherwise check the question
find the solubility of PbSO4 ( K = 1.1 * 10-8 ) in 0.1 M aqueous solution of KNO3
help needed badly . thanks guys.

1I dunno . whatever you post has to be substantiated by reasoning . I mself don't te answer ,just came across the Q . And as far as I know your answer seems doubtful to me.
106will PbSO4 and KNO3 form a complex? if yes then give the formula of complex (1st yr don know coordination compounds) if not then you can just calculate solubility as if it was a solution in water. This is because there will be no common ion effect to affect the solubility. Hence it can be treated as a normal problem
11pb and so4 ions will remain as it is since all the possible salts i.e. pb(no3)2 and k2so4 are
stng electrolyte, hence the solubility remains unaltered.(i.e√ksp)
1well this is out of JEE syllabus must have mentioned it . sry , and yeah I'll know the method but am not able to understand
1) find the ionic strength
2)find appropriate activity co-efficients
3)find solubility .
I'm a bit weak in physical chemistry , Nishant Manish , Gaurav would have studied these no ?
so help needed guys.
thanks
1look srinath if u want to have a clear idea about the theory and explanation part for the physical i can suggest the SHISHIR MITTAL'S book on physical chemistry but right now it is not recommended for you
the best is u go through only NCERT and thats enough and for in the later stage u will deal with this types of things if u got chemical engineering as ur stream and with the help of chemical potential u will learn to solve the problems
as the term activity is not something we knew in this stage so the things will come to u just wait .......
