Question

Question 9 (0.1 points) Which of the following salts have the highest and the lowest molar solubility in water? AgBr Ksp= 5*10-13 Ag2SO3 Ksp= 1.5*10-14 Ag3PO4 Ksp=1.8*10-18 LaF3 Ksp= 2*10-19 Mg3(PO4)2 Ksp=1*10-25 The lowest LaF3, the highest Ag2SO3 The lowest Ag2SO3, the highest Ag3PO4 The lowest AgBr the highest Ag3PO4 The lowest Mg3(PO4)2, the highest AgBr

Answer 1

Answer-

The molar solubility of a salt is directly proportional to the k_sp value.

This means that higher the k_sp value highest will be the molar solubility and vice-versa

Out of all these salts, the one which has highest k_sp value is AgBr

And the salty which has the lowest k_sp value is Mg₃(PO₄)₂

So the right option is-

d) The lowest Mg₃(PO₄)₂ , the highest AgBr
