If 30 ML of 5 $\times$ 10^-4 M Ca(NO₃)₂ Are Added to 70 ML of 2

question 69

Multiple Choice

If 30 mL of 5.0 $\times$ 10^-4 M Ca(NO₃) ₂ are added to 70 mL of 2.0 $\times$ 10^-4 M NaF,will a precipitate occur? (K_sp of CaF₂ = 4.0 $\times$ 10^-11)

• A)No,because the ion product is greater than K_sp.
• B)Yes,because the ion product is less than K_sp.
• C)No,because the ion product is less than K_sp.
• D)Not enough information is given.
• E)Yes,because the ion product is greater than K_sp.
