Question

64. Consider and their correspondin compound will have pounds with the generic formulas listed here responding molar solubilities in pure water. Which will have the smallest value of K.? lubility = 1.35 X 10M AX: molar solubility = 1 AX, molar solubili molar solubility = 2.25 X 10-4 M molar solubility = 1.75 X 10-4 M AX: mola . hr

Answer 1

Solubility Product (Ksp). It is defined as the product of concentrations of ions prodered from Imola of an electrolyte in a saturated solution. at a partiwlare ten perahure. This for an electrolyte like - AXBy F x 4+ + 18 If s is the soutility of salt (elecholyte) then concentration of Art in the solution will be s and we will 60 YS.
