Please walk me through the steps.

Answer 1

Answer #1

7)

concentration of Ca2+ = 1.0 x 10^-4 M

concentration of F- = 1.0 x 10^-4 M

CaF2 (s) ------------> Ca2+ (aq) + 2 F- (aq)

Q = [Ca2+][F-]^2

= (1.0 x 10^-4) (1.0 x 10^-4)^2

Q = 1.0 x 10^-12

Ksp = 4.0 x 10^-11

here Q < Ksp . so precipitate will not form

8)

CaF2 (s) ------------> Ca2+ (aq) + 2 F- (aq)

Q = [Ca2+][F-]^2

= (1.0 x 10^-4) (2.0 x 10^-4)^2

Q = 4.0 x 10^-12

Ksp = 4.0 x 10^-11

here Q < Ksp . so precipitate will not form
