(atomic mass: Ag=108; S=32, O=16, Pb=207; Br=80; Cl=35.5, N=14, Fe=56)
1) a) The evaporation of 860 ml of saturated solution of Ag2SO4 left 4.17g of Ag2SO4. What is the value of Ksp for Ag2SO4?
b) a saturated solution of lead(II) bromide, PbBr2 has a concentration of 0.4337% (m/v). What is a ksp for PbBr2 at 25°Celcius?
