1) Among the following equilibrium expressions for the dissolution of calcium fluoride (CaF_{2}) in water... the correct expression is?

a. K_{c }= [Ca^{2+}] [F^{-}] / [CaF_{2}] b. K_{sp }= [Ca^{2+}] [F^{-}]

c. Ksp= [Ca^{2+}] [F^{-}]^{2 }d. K_{c }= [Ca^{2+}] [F^{-}]^{2}/ [CaF_{2}]

2) 1 mg of solid AgCl is dissolved in water and as a result, the following equilibrium is established with an equilibrium constant value of K_{1}:

Once equilibrium is established, 9 g of AgCl is then added to the mixture. The equilibrium position shifts, and a new equilibrium is established with an equilibrium constant value of K_{2. }

_{}How are K_{1 }and K_{2 }related?

a. K_{1 }is greater than K_{2}

b. K_{2 }is greater than K_{1 }

c. K_{1 }is equal to K_{2}

d. K_{1 }and K_{2 }are not related
