Question

The Kp of PbBr, is 6.60 x 10 What is the molar solubility of PbBr, in pure water? molar solubility: м What is the molar solubility of PbBr, in 0.500 M KBr solution? molar solubility: M What is the molar solubility of PbBr, in a 0.500 M Pb(NO,) solution? molar solubility: м

Answer 1

Solution Given that : - ksp of plora = 6.60x10-6. ca) pbbro s) e s pot2+281 Molar Solubility, sporz] as (BY-] =2 ksp ={pot2] [Br] Ksp = [] [25]? Кsp = us? = 6.6x10 6 c ool. 867 M So, The Molar Solubility in pure water is [o ulo 7 ]m
