1) Among the following equilibrium expressions for the dissolution of calcium fluoride (CaF2) in water... the correct expression is?
a. Kc = [Ca2+] [F-] / [CaF2] b. Ksp = [Ca2+] [F-]
c. Ksp= [Ca2+] [F-]2 d. Kc = [Ca2+] [F-]2/ [CaF2]
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 K1:
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 K2.
How are K1 and K2 related?
a. K1 is greater than K2
b. K2 is greater than K1
c. K1 is equal to K2
d. K1 and K2 are not related
