a-1.0 x 10^-4
b- 4 x 10^ -1
c-1.0 x 10^10
d- 1.0 x !0^-10

Calculate the [H3O+] of a solution with pH =2
a- 2 x 10^-10
b-1 x 10^10
c- 1.0 x 10^+2
d- 1 x 10^-12
e- 1 x 10^-2

What is the solubility constant expression Ksp, for copper (II) hydroxiide, Cu(OH)2?
a-Ksp= [Cu^2+] [2OH-]
b-Ksp= [Cu^2+] [OH-]^2
c-Ksp= [Cu(OH)2]/[Cu^2+][OH-]^2
e-Ksp= [Cu^2+] [OH-]^2/[Cu(OH)2]
