Ani Ksp (Solubilly poodiet constant) is theequiliboium blysolid and its ind past despective ions in a soletion Higher the top, the more soluble the Ksp of Nicoz Ist past compound (all are mearsed Standard values that allae measured alase) Ksp of Pbfz = 3.7x108 at 25°c - is 6+6x109 A) Kop of Cas is 8x106 B) Ksp of Nis is 3x1021 c) Sp of Phy(10) is 3x10 D) Ksp of fez is 1.4x108 Accooding to the above standard values Nicoz is more souble than Bed [ie, NiS p.pr), A) ksp of BaSO4 = 11x10 B) tsp of Pb(OH) - 2.8x10 c) ksp of Cas = D) of PB According to the standard values, Pbf, is more soluble than AB (ie, Baso,, Pb(OH) pbt is less soluble than CD (ie, Cas, PbB 8x106 6.3x106 Nicoz is less soluble than Aie; as
