Question

When one litre of saturated solution of lead chloride, PbCl2 is evaporated to dryness, the residue is found to weight 4.5 g. Calculate the value of Ksp for Pbcl2

Answer 1

ksp=4s^3 how to find s ?

Answer 2

use algebra

Ksp/4=s^3

(Ksp/4)^(1/3)=s

Answer 3

@aaronq- i know
tell me how would u get s when ksp is not given -_-

Answer 4

Google ksp of PbCl2 to check if your answer's close to the theoreticsl value.

Answer 5

use the data given "1 L with 4.5 g PbCl2" to find the molarity - which is s.

Answer 6

thanx both of u :)
