Two mixtures are added into one flask at 25 °C, one mixture contains 0.55 mL of 0.75 M BaF2 and another 0.25 mL of 1.3 M Mg(OH)2. Ksp of Magnesium Fluoride, MgF2, is 7.4 x 10−9. Identify the correct option.
a) MgF2 solid will form
b) MgF2 solid forms, along with Mg+2 and F− ions
c) solution is unsaturated, precipitate does not form
d) solution is saturated, precipitate forms
