Answer:
CaF2 will not precipitate
Explanation:
Given
Volume of Ca(NO3)2 ml
Molar concentration of Ca(NO3)2
Volume of NaF ml
Molar concentration of NaF
Ksp for CaF2
CaF2 will precipitate if Q for the reaction is greater than ksp of CAF2
Moles of calcium ion
Moles of F- ion
Q is lesser than Ksp value of CaF2. Hence it will not precipitate
