Question

Does the Ksp change for the same salt under different conditions? Does the molar solubiltiy of a salt change under different conditions? Explain.

(For reference we're currently focused on common ion effect)

Data Table Each flask contains sufficient barium iodate solid to saturate the solution, plus: 1.00 M (no common ions) 1.00 M C: molarity of KIO3 1.00 M CB: molarity of Ba(NO3)2 molarity of standard Na2S2O3_GIU Flask 1: molarity of KNO 0.0250 M Flask 2: molarity of KNO3 0.0250 M Flask 3: molarity of KNO3 That sadiumthoulfate

Answer 1

No, the solubility product, K_{​​​​​​sp} never changes until and unless the temperature and the solvent has been changed.

The molar solubility may change in presence of other factors, such as common ions.

Ba(10), is a sparingly soluble salt. The ionic equilibrium is: Ba (303) Ksp Bath + 2105 Flask 1 a za Im=1 (No common ions) - -- Flask 2 2nt 0.0250 - - (Iog being common : wl lön, [103]- 0.0250 (m) - - - - - nt 0.025 Flash 3 - (Batz being common i n con, Bat] =8.0250 (m) - - - - for all condition, ksp= [Bat2] [103] - ax (292? If common ions are present, then it is clean that in order to keep the Sahubility product same, which is constant for a particular salt in a particular solvent at particular conditions.
